Chromatography without compromise In 00, Waters revolutionized how LC separations were performed by developing the ACQUITY UltraPerformance LC (UPLC ) system. High resolution UPLC separations are realized in a system that is capable of fully utilizing LC columns that are efficiently packed with pressuretolerant, sub- µm particles. The highly flexible ACQUITY UPLC system is known for its unique capability of not having to switch between the ultra performance liquid chromatography (UPLC) capability of UPLC mode and conventional HPLC mode since the same unit is capable of both without modification or upgrades. Since the 90 s chromatographers have been limited to LC systems that were capable of operating at maximum system pressures of only 000 psi (00 bar). This pressure limitation, coupled with large system volumes and slow data acquisition rates hindered the ability of separation scientists to fully realize the speed and efficiencies promised by using small (< µm) particles. The ACQUITY UPLC system shatters these operating limitations and is designed to operate at a maximum pressure of 000 psi (000 bar). Waters ACQUITY UPLC systems are holistically designed to dramatically improve resolution, sample throughput and sensitivity. Flexibility with UPLC Technology Speed, Sensitivity and Resolution Whether your objective is maximum speed or maximum resolution, UPLC technology provides you with the flexibility to achieve both.

the power of small particles at Higher Pressures Benefits of Holistic ACQUITY UPLC System and Column Design The potential chromatographic benefits that can be achieved when using sub- µm particle LC columns are not solely due to the particle size. To fully realize the promise of sub- µm particle performance, one must have an LC system that is capable of operating at the optimal linear velocity for the particle (and analyte). Further, this LC system must have an ultra-low system volume; a fast, sensitive, low-volume detector; intelligent software; negligible carryover; and, of course, the ability to reliably run at the higher backpressures generated by small particles operated at their optimal linear velocity. Simply put, this is what the ACQUITY UPLC system was designed to do: allow chromatographers to fully realize and harness the power and promise of sub- µm particle columns. The Benefits of UPLC Pressure Capability The ability to run at the optimal linear velocity is crucial to realizing the performance gains of sub- µm particle columns. In this example, four caffeine metabolites are run using the same chromatographic conditions (except flow rate as noted) on a fully optimized, microbore HPLC system vs. a standard ACQUITY UPLC system. The improvements in efficiency, resolution, peak shape and peak height illustrate the power of UPLC technology. Since the commercialization of the ACQUITY UPLC system in 00, other LC manufacturers that do not possess UPLC technology have subsequently claimed that one can achieve most of the performance (mainly speed) gains of UPLC technology by using small (e.g., µm) particle columns in a conventional LC system at HPLC pressures. Chromatographic theory indicates, however, that this claim is somewhat untrue. In 00, Waters described how one can achieve higher chromatographic throughput with the Intelligent Speed (IS ) family of HPLC columns. However, this was not UPLC technology, but rather fast LC based upon small HPLC particles packed into short columns at the expense of resolution. With UPLC technology, one need not compromise sample throughput for chromatographic fidelity. Waters is the first and only LC manufacturer capable of delivering upon the promise of sub- µm particle UPLC technology. 0.

Ultra-fast separations Ultra Speed How does one produce a short separation that does not sacrifice efficiency and/or peak shape? The simple answer lies in chromatographic theory. If one can reduce the column length, while simultaneously reducing the particle size by the same ratio (i.e., maintain column length to particle size (l/dp) ratio), the resolving power of the column as well as the resolution or peak capacity of the resulting chromatogram remains intact. However, this separation can be achieved in less time. The practical and commercial application of this simple chromatographic theory, however, has proven to be challenging. For the first time, UPLC technology allows separation scientists to fully realize the speed and efficiencies promised by short columns packed with very small particles: n Ultra-low system volume (low bandspreading) n Fast, efficient detector and/or mass spectrometer n Short cycle time sample manager with low carryover n Small, rugged, highly efficient particles n Advanced column hardware and packing techniques. Application areas that benefit from the fast separations that are possible with 0 mm length ACQUITY UPLC columns include confirmatory Active Pharmaceutical Ingredient (API) QC, stability monitoring, cleaning protocol validation, early drug development screening, bioanalytical analyses, content uniformity, drug release assays and process monitoring.

Ultra-High Resolution Separations Ultra Resolution Chromatographers are always looking for solutions that will deliver more resolution and more robust separations. To meet this need for higher efficiency, Waters developed 0 mm length ACQUITY UPLC columns. With these longer columns, challenging separations such as impurity profiling, metabolite ID analyses and drug stability monitoring can be run routinely with high resolution and moderate analysis times. The resolving power of an LC column can be expressed by its length to particle size ratio (l/dp). Columns with the highest l/dp ratios provide greater efficiencies (N) and are normally used in the most difficult separations. The l/dp ratio of the 0 mm length columns is more than 88,000, thus producing efficiencies of >,000 plates per separation. As a point of reference, a. x 0 mm, µm HPLC column has an l/dp ratio of 0,000 and can produce efficiencies of only,000 plates.

Ultra-Sensitive separations Ultra Sensitivity Novel or putative drugs often exhibit high potency resulting in the requirement for low dosage levels. Hence, determining LLQ levels in bodily fluids often present chemists with the challenge of achieving lower limits of detection when developing chromatographic assays for impurity profiling, bioanalysis and metabolite identification. Frequently there are several compounds of interest, all of which must be detected and quantitated in a single chromatographic run. High sensitivity separations can be developed and improved through the use of small i.d. columns in microbore dimensions (e.g.,.0 mm i.d.). Columns of these dimensions offer higher sensitivity over their larger diameter counterparts due to smaller analyte elution volume resulting in an increase in analyte concentration and subsequent increase in detector response. Microbore columns further have advantages in that they consume less mobile phase and can be more easily thermostatically controlled. Increased Sensitivity with.0 mm i.d.

Resolution Building Resolution with UPLC Technology The fundamental resolution equation for isocratic separations states that resolution (Rs) is proportional to the square root of column efficiency (N). Column efficiency (N) is inversely proportional to particle size (dp). Thus, smaller particles provide higher resolution. The highly efficient. μm BEH particles and.8 µm HSS particles allow chromatographers to maximize the efficiency (N) of their separation with the ACQUITY UPLC system. However, the fundamental resolution equation states that resolution can be improved by changing the selectivity (α) or retentivity (k). Lower efficiency (N) HPLC separations required chromatographers to randomly try many of the hundreds of different types of column chemistries in order to obtain an adequate separation. Since the efficiencies of UPLC separations may be - times higher, a smaller number of ligands and particles are necessary to provide the desired resolution. ACQUITY UPLC columns allow chromatographers to efficiently develop faster and more robust separations.

Innovation Industry-Leading Engineering and Manufacturing Columns optimized for UPLC separations require innovative hardware and manufacturing processes that are not apparent when simply looking at the outside of the column. Like the holistically designed ACQUITY UPLC system, attention to every detail is critical for chromatographic success. ACQUITY UPLC columns were designed to be an integral part of the low bandspread UPLC system. The column and system could not be developed by simply designing down or re-engineering an existing HPLC column or system. Typical HPLC system extra-column volumes and pressure limits would severely compromise the performance of UPLC columns. ACQUITY UPLC columns are the most technologically advanced columns ever created. Procedures for reproducibly producing and sizing commercial quantities of. μm and.8 µm particles had to be developed. New packing stations and methods had to be designed, invented and implemented since UPLC columns are packed and tested differently than HPLC columns. Additionally, UPLC instrumentation is necessary to test these columns, something that no other manufacturer possesses. Since UPLC technology was created with the future in mind, ACQUITY UPLC columns incorporate ecord technology a step towards the paperless laboratory. Besides storing each column s unique Certificate of Analysis, the ecord tracks column usage such as date of installation, number of injections, number of sample sets, maximum temperature and pressure that the column has been subjected to and the date that the column was last used. All of this information travels with the column and is easily printable. The ecord is permanently attached to the column and the data cannot be erased.

HPLC to UPLC Method Transfer Easily Migrate From HPLC to UPLC Technology In successful LC method migration, the selectivity of the original separation can be maintained, or improved, if desired. This requires careful consideration and understanding of such key parameters as column dimensions, system volumes and configurations, injection volumes, analyte molecular weight and gradient profiles. Without proper consideration of all these parameters, the transferred method results will not meet the desired expectations. For years, the necessary scaling calculations involved in method transfer were often performed manually, which is time consuming and can lead to errors. The ACQUITY UPLC columns calculator is an easy to use, yet powerful software tool that accurately handles the scaling calculations that are required to convert isocratic or gradient HPLC methods to UPLC methods. The calculator provides a selection of UPLC methods that the chromatographer can choose from what is most important: maximum speed, maximum resolution or a combination of both. ACQUITY UPLC Columns Calculator choices include: n UPLC methods where the selectivity and resolution of the original HPLC separation can be maintained n Faster UPLC methods that enable higher throughput and productivity without sacrificing resolution n Higher resolution UPLC methods that provide greater confidence in the results without requiring longer analytical run times.

Superior Lifetime and Reproducibility Rugged and Stable Columns The innovation of ACQUITY UPLC columns does not stop with the development of rugged and efficient particles and stationary phases. Another major focus is the production of stable UPLC columns that provide the longest possible lifetimes under demanding UPLC conditions. New column hardware is designed to minimize band broadening and ensure leak-free connections. An innovative frit design is implemented in order to keep particles in the column and out of the detector or MS source. New, proprietary column packing stations and processes are designed and developed to ensure a stable packed column bed and long, reproducible column lifetimes.

UPLC Column Protection VanGuard Pre-Columns Separation scientists working in demanding application areas such as bioanalysis, food/beverage, natural products, environmental and industrial chemicals analyze complex, unpredictable and challenging samples on a routine basis. These types of samples can have a negative impact on column lifetimes when appropriate sample preparation/cleanup procedures are not implemented. VanGuard Pre-columns are designed for these types of application areas where chemical and/or particulate contamination can shorten the lifetime of a UPLC column. Key Features and Benefits of VanGuard Pre-Columns VanGuard Pre-columns are the result of over two years of product development and are the first guard column devices designed for routine use at pressures up to 000 psi (000 bar) in applications run on the ACQUITY UltraPerformance liquid chromatography system. VanGuard Pre-columns feature a. mm i.d. x mm length, ultra-low volume design which efficiently protects UPLC column performance. This patent-pending design does not compromise the UPLC holistic design approach to higher efficiency, greater resolution and increased throughput since the same ACQUITY UPLC column stationary phases and column frits are used in VanGuard Precolumns. Since the VanGuard Pre-column connects directly to the inlet of the ACQUITY UPLC column, extra-column volumes are minimized and mobile phase leaks due to additional connections are all but eliminated.

UPLC Particle Technology ACQUITY UPLC Particle Technology There is more to creating a UPLC particle than synthesizing a small particle. Many HPLC particles do not possess the mechanical stability and structural integrity to withstand UPLC operating pressures (e.g., 000 psi/000 bar). Why is pressure tolerance important? In order to realize the efficiency gains of sub- µm particles, the ability to routinely operate at higher linear velocities (e.g., higher flow rates) is required. These higher linear velocities combined with small, sub- µm particles result in higher operating backpressures. Waters has created two highly efficient, pressure-tolerant UPLC particles: the. µm Ethylene Bridged Hybrid (BEH) particle and the.8 µm High Strength Silica (HSS) particle. The first ACQUITY UPLC particle created was the. µm Ethylene Bridged Hybrid (BEH) particle. This second generation hybrid particle is one of the key enablers behind UPLC technology and is available in five column chemistries: C 8, C 8, Shield RP8, Phenyl and HILIC. Because this is a hybrid particle, a wider usable ph range (up to ph ) makes method development faster and easier. BEH particles are also available in HPLC particle sizes (.,., and 0 µm) in the XBridge family of HPLC columns, thus allowing seamless transfer between HPLC and UPLC separations. ACQUITY UPLC HSS column chemistries include, SB (Selectivity for Bases) and T. The chemistry is a fully endcapped, ultra-performance, general purpose C 8 bonded phase that provides superior peak shape for bases, increased retentivity (vs. ACQUITY UPLC columns), and extremely long lifetimes under acidic conditions. The SB (Selectivity for Bases) chemistry is an unendcapped C 8 bonded phase designed and optimized for low ph method development and offers alternate selectivities, especially for basic compounds, as compared to most modern, high coverage C 8 chemistries. The HSS T chemistry is an aqueous mobile phase compatible C 8 bonded phase that is designed to retain and separate small, water soluble, polar organic molecules, much like Atlantis T HPLC columns.

UPLC Particle Technology BEH Technology In 999, Waters launched the XTerra family of HPLC columns featuring first generation hybrid particle technology (HPT). HPT enabled XTerra columns to become one of the most successful column products in the history of Waters. In HPT, the best properties of inorganic (silica) and organic (polymeric) packings are combined to produce a material that has superior mechanical strength, efficiency, high ph stability and peak shape for bases. The BEH Particle: ne of the Key Enablers of UPLC Technology Ethylene Bridges in Silica Matrix The first generation methyl hybrid particles of XTerra columns did not possess the mechanical strength or efficiency necessary to fully realize the potential speed, sensitivity and resolution capabilities of UPLC technology. Therefore, a new pressure-tolerant particle needed to be created. A new, second generation hybrid material was developed which utilizes an ethylene bridged hybrid (BEH) structure. Compared to the first generation methyl hybrid particle of XTerra columns, the BEH particle of ACQUITY UPLC BEH columns exhibits improved efficiency, strength and ph range. BEH Technology is a key enabler behind the speed, sensitivity and resolution of UPLC separations. E t C H C H E t E t S i S i S i S i S i E t Polyethoxysilane (BPES) Anal.

Waters material scientists developed a new High Strength Silica (HSS) particle with the high mechanical stability and appropriate morphology necessary to provide long column lifetimes and UPLC efficiencies at pressures up to 000 psi (000 bar). This.8 µm UPLC HSS particle is designed and tested specifically for use in UPLC separations. ACQUITY UPLC HSS columns contain the first and only 00% silica particle designed, tested and intended for use in applications up to 000 psi/000 bar. The new ACQUITY UPLC HSS particle is not an HPLC particle. High pore volume HPLC particles do not posses the mechanical stability necessary to withstand the high column packing and operating pressures of UPLC separations. Designing and Testing Pressure-Tolerant UPLC Particles In this proprietary Waters particle strength test, chromatographic particles are packed into a column and mobile-phase flow is applied. As pressure increases, the particles are crushed, thereby restricting flow. The degree of deviation from the Ideal Profile line indicates particle fragility/ strength.

BEH (Ethylene Bridged Hybrid) Chemistries ACQUITY UPLC and C 8 Columns The vast majority of reversed-phase (RP) LC separations take place on columns that contain C 8 or C 8 bonded stationary phases due to their stability, retentivity and reproducibility. In addition, these hydrophobic ligands provide the desired separation most of the time. ACQUITY UPLC and C 8 columns were designed to be the columns of choice for most UPLC separations by providing the widest ph range and efficiencies. They incorporate trifunctional ligand bonding chemistries which produce superior low ph stability and ultra-low column bleed. This low ph stability is combined with the high ph stability of the. μm BEH particle to deliver the widest usable ph operating range. In addition, these new chemistries also utilize new, proprietary endcapping processes which produce outstanding best peak shape for bases. These bonding chemistries and particle synthesis innovations produce the sharpest peaks, highest efficiencies and maximum MS sensitivities. Robust Separations EPA Method 80 HPLC separations usually require temperature control of ± C since large shifts in selectivity can occur with small changes in temperature.

BEH (Ethylene Bridged Hybrid) Chemistries ACQUITY UPLC BEH Shield RP8 Columns Embedded polar group reversed-phase LC columns contain stationary phases that combine the hydrophobicity of an alkyl ligand with the hydrophilicity of an embedded polar group. Features of embedded polar group columns include alternate selectivities as compared to alkyl chain LC columns, excellent peak shape for bases and aqueous mobilephase compatibility. ACQUITY UPLC BEH Shield RP8 columns are designed to provide selectivities that complement the ACQUITY UPLC C 8 and C 8 phases. ACQUITY UPLC Shield RP8 columns combine Waters patented Shield Technology with BEH Technology by incorporating an embedded carbamate group into the bonded phase ligand. The alternate selectivity and excellent peak shape from the embedded polar group ligand, when combined with the wide ph range and ultra-efficiency of the. μm BEH particle, provide a powerful tool for UPLC method development. Fast Separations of Basic Drugs Challenges involving the separation of basic compounds using reversed-phase LC include poor analyte peak shape and retention.

BEH (Ethylene Bridged Hybrid) Chemistries ACQUITY UPLC BEH Phenyl Columns Phenyl-ligand containing reversed-phase columns can provide complementary selectivities as compared to other straightchain alkyl stationary phases, especially for analytes that contain aromatic rings. Traditional weaknesses of phenyl ligands include poor ph stability, reproducibility and peak shape. ACQUITY UPLC BEH Phenyl columns were designed to overcome these weaknesses and provide complementary selectivities, outstanding ph stability and excellent peak shape for all compounds. They utilize a trifunctional C alkyl tether between the phenyl ring and the silyl functionality. This phenyl-hexyl ligand, combined with the same proprietary endcapping processes as the ACQUITY UPLC and C 8 columns, provides ultra-low column bleed, long column lifetimes and excellent peak shape. This unique combination of ligand, endcap and. μm BEH particle creates a new dimension in selectivity and efficiency for challenging UPLC separations. Caffeic Acid Derivatives in Echinacea Purpurea Separations The active components in various Echinacea preparations can be divided into three major groups: caffeic acid derivatives, polysaccharides, and lipophilic components. Studies have shown that there is variation in the quality of popular Echinaceacontaining products. Thus, monitoring of the active ingredients is desired.

BEH (Ethylene Bridged Hybrid) Chemistries ACQUITY UPLC BEH HILIC Columns Hydrophilic Interaction Chromatography (HILIC) is a technique used to retain and separate very polar compounds that cannot be retained using reversed-phase chromatography. HILIC is also referred to as aqueous normal phase or reverse reversed-phase since the elution order is that of normal phase (non-polar analytes elute first) and the solvents are similar to those of reversed-phase chromatography. The ACQUITY UPLC BEH HILIC columns contain the rugged. µm unbonded BEH particles and are designed to retain and separate very polar basic compounds. These unique columns are optimized and tested to produce efficient and reproducible separations under UPLC HILIC conditions. ACQUITY UPLC BEH HILIC columns overcome a major weakness of HILIC stationary phases: chemical stability. Silica-based HILIC phases are often chemically unstable. The rugged BEH particle s wide usable ph range overcomes this chemical instability and results in long column lifetimes. Hydrophilic Interaction Chromatography (HILIC) is a separation technique where a polar stationary phase is used with a mobile phase that contains a high concentration of non-polar (organic) solvent and a low concentration of polar (aqueous) solvent. HILIC is used when compound retention is not possible using traditional reversed-phase LC. HILIC is quickly gaining popularity as a powerful separation technique since the mobile phases used contain high concentrations of organic modifier (e.g., ACN) which are ideal for compound ionization by ESI-MS. This results in much higher sensitivity and lower limits of detection. Separation of Very Polar Bases Using ACQUITY UPLC BEH HILIC Columns pioid pain relievers such as morphine are used to manage chronic and acute pain. These types of drugs are extremely potent, resulting in low doses and concentrations in body fluids. The study of the efficacy and metabolism of morphine and its metabolites within the body requires selective and sensitive analytical methods such as Hydrophilic Interaction Chromatography (HILIC). In the HILIC separation shown below, the more polar metabolite morphine--β-glucuronide elutes AFTER the more non-polar parent compound, morphine.

HSS (High Strength Silica) Chemistries ACQUITY UPLC Columns As chromatographers around the world continue to realize and embrace the benefits of UPLC technology, additional UPLC column choices which provide complementary selectivities are needed to facilitate method development and provide application-specific solutions. Alternate or complementary selectivities can be realized by using columns with different bonded phases and/or different particle substrates. Based upon customer feedback, Waters created an additional pressure-tolerant UPLC-compatible particle to complement the. µm Ethylene Bridged Hybrid (BEH) particle. The.8 µm High Strength Silica (HSS) particle is designed to provide 'silica-like' selectivities and retentivity. The ACQUITY UPLC chemistry which is a fully endcapped, high coverage, ultra-performance C 8 bonded phase that provides superior peak shape for bases, increased retention (vs. ACQUITY UPLC columns), and excellent low ph stability. Although there is no direct HPLC column analog for ACQUITY UPLC columns, chromatographers will discover that for many separations, the selectivities and retention observed when using ACQUITY UPLC columns will resemble the chromatography produced by many modern, silica-based C 8 HPLC columns. ACQUITY UPLC Columns Provide Superior Peak Shapes The efficiencies and separations possible with UPLC technology are the result of more than just small particles. State-ofthe-art bonding and endcapping processes are combined with small, rugged and efficient sub- µm particles to produce narrow, symmetrical peaks that enable fast, high resolution separations. The two Waters UPLC C 8 chemistries produce efficiencies of greater than 00,000 plates/m for the strong base amitriptyline (pk a 9. at ph ) demonstrating that there is more to UPLC separations than sub- µm particles.

HSS (High Strength Silica) Chemistries ACQUITY UPLC Columns Creating st century separations involves more than small particles that operate at higher pressures. The ultraefficiencies, peak capacities and column lifetimes obtained in UPLC separations can only be achieved using columns packed with stationary phases that utilize innovative and industry-leading bonding and endcapping processes. A small particle bonded with a poor and/or outdated stationary phase and/or endcap will produce inadequate efficiencies, inferior resolution and short column lifetimes. Like all ACQUITY UPLC stationary phases, the ACQUITY UPLC columns are created using state-of-the-art bonding and endcapping processes that produce high efficiencies and long column lifetimes. The ACQUITY UPLC stationary phase features a tri-functionally bonded C 8 ligand and proprietary endcapping process that not only yields superior peak shapes for bases at neutral ph, but also resists acid hydrolysis, thus providing extremely long lifetimes at low ph. Since the HSS particle is 00% silica, the new ACQUITY UPLC HSS C 8 chemistry is designed to work and excel under demanding highly acidic conditions. The ability to reliably operate at low ph (i.e., <ph ) is important because ph manipulation is a key tool in controlling and manipulating selectivities of ionizable compounds during method development. The ACQUITY UPLC packing is the most stable bonded phase commercially available and does not suffer from peak shape issues that plague older stationary phases that rely upon steric protection (and lack of endcapping) to produce stability at low ph.

HSS (High Strength Silica) Chemistries ACQUITY UPLC SB (Selectivity for Bases) Columns ACQUITY UPLC SB columns were designed specifically for chromatographers who routinely screen and categorize UPLC column chemistries as part of their method development protocols. Intended for low ph separations which contain complex mixtures of basic and non-basic compounds, ACQUITY UPLC columns can produce separations that will be quite different in terms of selectivities as compared to most modern, high coverage, fully endcapped C 8 stationary phases. How was this accomplished? Waters material scientists bonded a trifunctional C 8 ligand at an intermediate ligand density (i.e.,. µmol/m ) without endcapping. In general, the higher silanophilic activity will promote longer retention for basic compounds whereas the intermediate C 8 ligand density will produce slightly shorter (or equivalent) retention for non-basic compounds as compared to most modern high coverage, fully endcapped C 8 stationary phases. Chromatographically, this unique combination will provide a practical method development tool for complex UPLC separations. Fast Separations of Tricyclic Antidepressants Tricyclic antidepressants (TCAs) are secondary and tertiary amines and were commonly prescribed to patients suffering from depression or other conditions. TCAs are being replaced by selective serotonin reuptake inhibitors (SSRIs). ACQUITY UPLC HSS C 8 SB columns retain basic compounds such as tricyclic antidepressants longer than fully endcapped stationary phases due to the enhanced silanol activity on the non-endcapped HSS particle.

HSS (High Strength Silica) Chemistries ACQUITY UPLC SB (Selectivity for Bases) Columns Stationary phases have evolved from the large, irregularly shaped particles of the past to the small, spherical particles of the present. Along the way, bonding and endcapping technologies have advanced and improved as well. Material scientists have focused much effort on improving peak shape for basic compounds in reversed-phase separations. For example, embedded polar group stationary phase columns were created in the 990s to provide symmetrical peaks for basic compounds. The vast majority of reversed-phase separations take place on straight alkyl chain C 8 column chemistries. High ligand density bonding processes along with exhaustive endcapping are often implemented in order to reduce unwanted peak tailing and efficiency loss for basic compounds caused by secondary silanol interactions. Whereas the peak shape for basic compounds improves as a result of these advanced bonding and endcapping procedures, the resulting selectivities for these C 8 chemistries end up being quite similar. This can be seen by noting the large population of hydrophobic C 8 column chemistries located in the lower right quadrant of the Waters Reversed-Phase Column Selectivity Chart. As can be seen in the Waters Reversed-Phase Column Selectivity Chart below, ACQUITY UPLC SB columns do not resemble the selectivities provide by most high coverage, fully endcapped C 8 bonded phases. This selectivity difference is valuable in developing UPLC methods. Waters Reversed-Phase Column Selectivity Chart In the Waters Reversed-Phase Column Selectivity Chart, the selectivity (α) for a non-polar base/neutral pair (amitriptyline/ acenaphthene) is plotted against the retention (k) of the non-polar, neutral compound acenaphthene under ph operating conditions. This chart can be used to compare HPLC and UPLC columns of similar (or different) selectivities. For more information on this chart, please see U. D. Neue, B. A. Alden, T. H.

HSS (High Strength Silica) Chemistries T Bonding for Polar Compound Retention ACQUITY UPLC HSS T columns utilize Waters innovative and proprietary T bonding. This is the same advanced bonding process that is behind the industry-leading polar-compound retention, aqueous mobile phase compatibility and ultra-low MS bleed of Atlantis T HPLC columns. T bonding utilizes a trifunctional C 8 alkyl phase bonded at a ligand density that promotes polar compound retention and aqueous mobile phase compatibility. The T endcapping is much more effective than traditional trimethyl silane (TMS) endcapping. This unique combination of bonding and endcapping provides superior polar compound retention and aqueous compatibility while also enhancing column performance, lifetime, peak shape and stability. Although the rugged and efficient ACQUITY UPLC BEH particle provides a wide ph range and superior peak shapes, its hydrophobic nature does not promote polar compound retention. ACQUITY UPLC HSS T columns are designed to retain and separate polar organic compounds in reversed-phase UPLC separations. When compared to ACQUITY UPLC columns, most compounds are more strongly retained on ACQUITY UPLC HSS T columns. Features of the ACQUITY UPLC HSS T columns include: n Superior polar and non-polar compound retention Superior Retention of Polar Compounds ACQUITY UPLC HSS T columns retain polar compounds longer than ACQUITY UPLC columns and contain one of the most retentive sub- µm column chemistries commercially available. n Aqueous mobile phase compatibility n Ultra-low MS bleed n Additional selectivity choice for UPLC separations. 0.00.00.00.00.00 HSS T BEH C 8 BEH Shield RP8 BEH Phenyl 0.00.00.00.00.00 BEH HILIC SB Columns:. x 0 mm Mobile Phase A: 0 mm CH CNH, ph.0 Mobile Phase B: ACN Flow Rate: 0.8 ml/min Isocratic Mobile Phase Composition: % B Injection Volume: 0. µl Temperature: 0 C Detection: UV @ 80 nm Instrument: ACQUITY UPLC System with ACQUITY UPLC 99 PDA Compounds.
