hplc columns introduction HPLC Column Selection A Comparison of Reversed-Phase Columns Based on the widely accepted work and data of Drs. Lloyd Snyder and John Dolan., Grace has developed this column selection tool for choosing reversed phase HPLC columns based on peak capacities and column selectivity of polar and nonpolar compounds. Typically, chromatographers choose HPLC columns by comparing physical characteristics, such as surface area and carbon load. Often, this does not provide enough information about selectivity or capacity for adequate column selection. This chart provides a reliable means of choosing HPLC columns based on acidic, basic, and hydrophobic character. The Snyder/Dolan column test procedure has been described in a series of publications. Based on retention data for a series of standard mixtures and the same separation conditions (0% acetonitrile/buffer; ph.8 and 7.0; C), reversed-phase columns are characterized by five column-selectivity parameters: hydrophobicity (H), steric interaction (S*), hydrogen-bond acidity A, basicity (B), and relative silanol ionization or cation-exchange capacity C. Here we have chosen to graphically highlight data for H, A, and C, with C results at ph 7.0. Hydrophobicity (H) is often the primary analyte interaction with reversed phase columns and indicates overall capacity. Secondary interactions are often polar interactions with basic analytes. The degree of unprotonated base interaction A and protonated base interaction C with the packing material is measured and represented here. Directions for Using the Column Chart The chart lists the columns in descending order of hydrophobic capacity (H). To find similar HPLC columns to test as back-up columns, follow these steps. ) Find the column you are currently using and note neighboring columns which have similar (H) capacity factors. ) Compare the values for interaction of polar compounds ( A and C ). If there is more than one choice for a back-up column, then compare your actual sample to the test probes. If your sample is nonpolar, then place more emphasis on hydrophobic values. If your sample is basic (polar), then pay special attention to A and C and determine if your sample will be protonated ( A) or unprotonated (C ) and place greater emphasis on one of these values.

hplc columns introduction High Throughput HPLC Introduction The Benefits of Grace Small Particles and Formats Today s laboratories are under greater demand to analyze more samples in less time. To help meet this demand, major product advances have been made to decrease analysis time and increase HPLC throughput. HPLC system advances have greatly reduced the influence of extra column volumes and have extended the range of flow rates and pressure capabilities. In response to this, Grace now offers a wide range of column chemistries and formats appropriate for all types of high throughput systems. The use of smaller particles offers two main improvements to the chromatographic separation increased resolution and speed. Resolution is directly proportional to the square root of column efficiency, therefore the higher the efficiency, the narrower the peaks and the greater the resolution between them. Increased speed comes from higher mobile phase flow rates that can be used without loss in efficiency, and higher flow rates mean faster analysis times. Understanding the type of system currently in use for high throughput separations and then matching the right column configuration is critical to achieving the best high throughput separation. Here we outline the three types of systems currently in use today for high throughput and the recommended HPLC column format for use with that system. System Type Ultra High-Pressure LC System (>0,000psig pressure limitation) Examples: Agilent 00, Waters Acquity, Thermo Accela, Jasco XLc. Speed from Ultra High-Pressure Systems: Representing the latest in LC instrumentation technology, ultra high-pressure systems theoretically have the potential to deliver the fastest separations. They have minimal system volume and offer a pressure limit upwards of,000psig. This allows the use of columns with sub µm particles and 7 times traditional flow rates. Sub µm particles extend the working range of acceptable mobile phase linear velocities without sacrificing efficiency. Therefore, you can push flow rates and still get equal or better performance. Suggested Column Format: VisionHT columns are designed for microbore and ultra high-pressure LC systems that have small system volumes to limit peak broadening from sample diffusion. VisionHT columns are packed with highly efficient.µm phases that yield taller peaks and increase sensitivity. The column hardware incorporates a low dead volume design to minimize sample diffusion, and maintain peak integrity and efficiency.,000psig high-pressure stability allows fast flow rates, decreasing run times 0 fold.

System Type Low Volume, High Throughput (HTP) LC System (<0,000psig Pressure Limitation) Examples: Shimadzu Prominence UFLC, Hitachi Ultra, LC Packings UltiMate, Surveyor Plus Speed from Low-Volume HTP LC Systems: These systems concentrate on reducing the cycle time between injections thus allowing more injections per time frame. Typically they employ high-speed gradient pumps, fast autosamplers and a quick detector sampling rates. They are not pressure rated to the extremes of ultra high-pressure systems, but the low system volume allows for short columns of narrow i.d. Suggested Column Format: Expedite and VisionHT columns are designed for microbore high throughput LC systems that have small system volumes. These formats incorporate a low dead volume design so that sample bands do not diffuse within the column hardware, maintaining peak integrity and efficiency. Expedite columns are packed with highly efficient.µm or µm in very short column lengths to minimize backpressure and reduce analysis times. Though not as fast as ultra highpressure LC systems these systems and columns balance both speed and backpressure. System Type Recommended Column Formats: Length: i.d.: 6 7 Expedite and VisionHT 0, 0, 0, 0mm,,.6mm 6 Expedite Columns for Low Volume High Throughput LC 076. Ribonuclease (7ng). Bovine Insulin (7ng). Cytochrome C (7ng). Lysozyme (ng). Bovine Serum Albumin (7ng) 6. Carbonic Anhydrase (7ng) 7. Ovalbumin (7ng) System Type Traditional LC System (<000psi Pressure Limitation) Examples: Agilent 00, Waters Alliance, Thermo Surveyor, Dionex Ultimate, Shimadzu Prominence, Hitachi LaChrom Speed from Traditional LC Systems: To get speed from a traditional LC system, you need to consider the 000psig pressure limitation, and the typically large ml system volume. High throughput columns on this system need to deliver a highly efficient separation typically achieved with a small particle packing ( µm), but without the high backpressures. The large system volume also needs to be balanced with an equally large column volume or the separation will be plagued with extra-column effects. Suggested Column Format: Rocket columns provide low backpressure and fast analysis times while preserving column efficiency. They are available with both.µm and µm packing materials for use on standard HPLC systems with backpressure limits less than 000psig. The 7mm i.d. allows faster flow rate that sweep the extra system volume faster and reduce peak broadening. This larger diameter also means a larger column volume to system volume ratio to minimize the efficiency loss from extra system volume. This benefit is more pronounced over. and mm i.d. columns that have a smaller ratio than.6mm i.d. columns and require much lower flow rates for acceptable backpressures. Low flow rates allow more time for sample diffusion within the standard HPLC s system volume to further degrade the column s efficiency.

Grace VisionHT Ultra High-Pressure Columns Comprehensive High Purity.µm Selectivity Options Sub µm particles deliver efficiency and speed, but critical to success is having the right stationary phase selectivity. Six VisionHT high purity phases are available, each with unique separation benefits. C8-HL, with maximum bonded phase coverage, is ideal for complex hydrophobic samples. Use C8-B for basic compounds at neutral ph, often a requirement for mass spec work in the pharmaceutical industry. Reserve the C8 and C8-P for fastest analysis times. Both offer increased polar interactions to make neutral, non-polar compounds elute faster and retain polar compounds longer. The HILIC and Silica packings are normal phases that typically use near exclusive organic mobile phases; an advantage when seeking highest mass spec sensitivity. VisionHT phases have exceptionally rigid silica structure that withstands routine use of,000psig pressure often required in this new technology. Reproducible silica synthesis, bonding and column packing guarantee low bleed and excellent column-to-column consistency.

Grace VisionHT Ultra High-Pressure Columns Protect Your UHPLC Column Investment The smaller diameters and finer porosity frits required in UHPLC creates a higher likelihood of column and system blockage. Trace contaminates not normally problematic for traditional LC, may now pose backpressure issues. VisionHT guards protect your column to minimize down time and reduce cost. Two guard formats available: Integral and stand-alone. Couple the zero-dead volume integral guard directly to any VisionHT column, and realize absolutely no loss in efficiency. Use the stand-alone version to protect other manufacturers UHPLC columns, or as an on-line enrichment device. Prevent Column Blockage with Integral Guards with guard without guard 0 0..0..0 Min. No loss in efficiency. VisionHT Integral Guard System N=7K/m Replace existing endfitting with the integral guard endfitting. Change guard cartridges as necessary. 76 VisionHT Ultra High-Pressure Columns Packing Format i.d. x Length Part No. C8-HL,.µm Ultra High-Pressure x 0mm 0 Ultra High-Pressure x 0mm Ultra High-Pressure x 0mm Ultra High-Pressure x 00mm Ultra High-Pressure x 0mm Ultra High-Pressure x 0mm Ultra High-Pressure x 0mm 6 Ultra High-Pressure x 00mm 7 C8-B,.µm Ultra High-Pressure x 0mm 90 Ultra High-Pressure x 0mm 90 Ultra High-Pressure x 00mm 90 Ultra High-Pressure x 0mm 90 Ultra High-Pressure x 0mm 906 Ultra High-Pressure x 0mm 907 Ultra High-Pressure x 0mm 908 Ultra High-Pressure x 00mm 909 C8,.µm Ultra High-Pressure x 0mm 9 Ultra High-Pressure x 0mm 99 Ultra High-Pressure x 0mm 960 Ultra High-Pressure x 00mm 9607 Ultra High-Pressure x 0mm 97 Ultra High-Pressure x 0mm 9600 Ultra High-Pressure x 0mm 960 Ultra High-Pressure x 00mm 9609 C8-P,.µm Ultra High-Pressure x 0mm 96 Ultra High-Pressure x 0mm 960 Ultra High-Pressure x 0mm 960 Ultra High-Pressure x 00mm 9608 Ultra High-Pressure x 0mm 98 Ultra High-Pressure x 0mm 960 Ultra High-Pressure x 0mm 9606 Ultra High-Pressure x 00mm 960 HILIC,.µm Ultra High-Pressure x 0mm 90 Ultra High-Pressure x 0mm 9 Ultra High-Pressure x 0mm 9 Ultra High-Pressure x 00mm 9 Ultra High-Pressure x 0mm 96 Ultra High-Pressure x 0mm 97 Ultra High-Pressure x 0mm 99 Ultra High-Pressure x 00mm 90 SI,.µm Ultra High-Pressure x 0mm 9 Ultra High-Pressure x 00mm 9 Ultra High-Pressure x 0mm 9 Ultra High-Pressure x 00mm 9 Stand-Alone Guard System In-line guard system expands applications beyond column protection.

A simple acidic phosphate buffer and a Prevail OA column at ambient temperature will separate short-chain organic acids in less than 6 minutes. Use ph to adjust column selectivity. Lowering the mobile phase ph progressively suppresses the ionization of the carboxylic acids, making them more hydrophobic. This gives you the ability to move these peaks relative to other peaks in the chromatogram, and it simplifies method development. 8 Figure - Organic Acids. Oxalic Acid. Tartaric Acid. Formic Acid 67.

Alltech Platinum Columns For Challenging Separations Unique selectivity Better peak shapes with polar analytes More separation choices with dual-selectivity Excellent stability and reproducibility.µm high throughput media for speed and resolution, especially when combined with Rocket and Expedite hardware The Platinum Column Advantage Controlled silica exposure is the difference that makes Platinum columns unique. Instead of thoroughly covering the silica with bonded phase to hide the silica, the exposure of the silica in Platinum columns is controlled to provide a dual mode separation with both polar and non-polar sites exposed to your samples. This extends polar selectivity well beyond what other reversed-phase columns offer and gives separations other columns cannot. Standard Platinum Columns vs Platinum EPS Columns Platinum columns come in two varieties offering different levels of silica exposure. Standard Platinum has a moderate silica exposure and is best used with neutral and moderately polar compounds. Platinum EPS (Extended Polar Selectivity) has a high level of silica exposure and is best used with compounds containing more than two polar functional groups.

GraceAlpha Columns (Patent Pending) A New Silica Generation High-porosity surface increases mass transfer and results in increased column efficiencies and loading capacity Dense core and highly spherical shape yields mechanically robust particle Proprietary bonding technology gives unique selectivity and increased resolution Ideally suited for scale up to prep applications Extreme Porosity High-porosity exterior increases mass transfer leading to higher efficiencies and superior loading capacity. The high-porosity structure adds an elastic quality to the silica surface allowing the particles to pack tighter yielding higher efficiencies. It also stabilizes the packed bed preventing voids. Dense Inner Core new Dense core provides exceptional strength. Typically the high-porosity structure would result in a weak particle prone to breaking, but the GraceAlpha particle combines the high porosity outer region with a dense inner core that results in a particle that resists breaking and forming fines that contribute to high backpressures.

Vydac Venture Immunoaffinity Columns Repetitive-Use, Silica-Based Immunoaffinity Columns Venture immunoaffinity HPLC columns provide an easy and quick way to purify and concentrate analytes from complex food, environmental, and biological matrices for fast, accurate measurement. 6908 Vydac Venture immunoaffinity columns use ICEtech (Inert Coating Enhancement Technology, U.S. Patent No. 6,80,966) silica processing to eliminate non-specific binding on the silica surface. This enables Venture columns to be the first affinity matrix to take advantage of silica s rigid porous structure, making direct coupling of the columns with other modes of chromatography, such as reversed-phase HPLC feasible.

Astec Amino and Reversed-Phase Columns Durable vinyl alcohol copolymer Stable from ph Stable and reproducible performance Choose Astec amino columns for separating mono- and oligosaccharides. Astec s polymer base makes these columns much more stable than silica-based amino columns. Choose Astec reversed-phase columns for amines and high recoveries of proteins and peptides. Because there are no silanols, elution order is always based on hydrophobicity of the analytes rather than polar interactions with the base material. High recovery of proteins and peptides is typical even at low sample loads. Mono-, Di-, and Trisaccharides 6 90. Rhamnose. Fructose. Glucose. Sucrose. Maltose 6.

Often pretreatment does not remove protein thoroughly. Drugs in biological fluid are hard to analyze because protein co-elutes with the component of interest. The target drug receives ion suppression from the protein and appears as a small peak. ODP HP can separate the target drug from protein by eluting protein early. The result of barbital analysis with BSA using microbore is shown as below. Barbital was introduced into the MS by a switching valve after BSA was eluted, and barbital was detected without any influence of ion suppression.,800k,600k,00k,00k,000k 800K 600K 00K 00K 0K 0K 0K 00K 90K 80K 70K 60K 0K 0K 0K 0K 0K 0 Valve Switch Barbital 0K 0K 0K 00K 90K 80K 70K 60K 0K 0K 0K 0K 0K 0 Valve Switch Barbital,800K BSA,600K,00K MS,00K,000K 800K 600K 00K 00K 0 UV 0 UV 0 0..0..0..0..0.

hplc columns large molecule Vydac MS Columns Excellent Peak Shape with Little or No TFA It is common practice for protein and peptide separations to include an acidic modifier such as TFA in the mobile phase. TFA masks basic entities, reducing mixed-mode retention, and improving peak symmetry. TFA also changes retention and selectivity for different analytes, and its concentration can be adjusted to optimize a separation. Unfortunately TFA is UV absorbent and contributes background at low UV wavelengths. Also It is especially problematic with electrospray MS where it interferes with ion generation, called quenching, and reduces MS sensitivity. 0.6 AU 0. 0. 0 0 Columns: 0.% TFA Flow Rate: Mobile Phase: Gradient: Detector: Peptides on 8MS C8 Reversed-Phase 0.0% TFA 0.0% TFA 0.0% TFA.

hplc columns large molecule Vydac Everest Columns Introduction High Resolution for Complex Peptide Samples High resolution of complex peptide digests Unique selectivity for both hydrophilic and hydrophobic peptides Exceptional microbore sensitivity with little or no TFA in the mobile phase Everest columns provide exceptionally high resolution for complex peptide digest separations. Unique selectivity and sensitivity are the result of new bonding technology that improves C8 surface coverage and deactivates residual silanols. Previously, the best 00Å C8 chemistries have had carbon coverage in the.8 to.6µmol/m range. Everest C8 coverage is in excess of µmol/m and approximates the theoretical limit based on surface area. This increased shielding of the base silica increases column life and reduces the amount of TFA required to shield the silica.

For a tryptic digest of Cytochrome C, an Everest column offers unique selectivity which allows the best separation of a group of hydrophilic and hydrophobic peptides. To assess resolution, chromatograms of tryptic digests of several proteins on an Everest column and several other commercial 00Å C8 reversed-phase columns were compared. Peak counts were based on detection by automated chromatography software with parameters set identically for all columns. In the analyses of a tryptic digest of cytochrome c, specific regions of the chromatogram were examined for the number of peaks resolved. The Everest column demonstrated unique selectivity for both hydrophilic and hydrophobic peptides.

Vydac ProZap C8 Ultra Fast Protein and Peptide Separations 0 times faster bioseparations than traditional column formats Ultra-high efficiency.μm packing Fast protein and peptide separations with conventional HPLC systems ProZap.μm, 00Å packings are ideal for fast bioseparations in life science applications. The combination of ProZap packings and short, 0mm Expedite column hardware delivers not only faster sample throughput, but also low back pressures suitable for conventional LC systems. Optimization of Gradient Parameters for Fast Protein Analysis Short ProZap columns are the perfect tool for fast reversed-phase protein separations. Under gradient conditions, longer columns only increase run time and do not increase resolution to improve the separation. Proteins adsorb at the head of the column and then desorb once the critical mobile phase concentration is reached. Since the proteins do not interact with the full length of the packed bed, short columns are sufficient for full resolution. Therefore, proteins of broad molecular weight ranges can be separated in less than one minute by combining short columns, higher flow rates, and fast, modified gradients. For best results high-pressure mixing should be used with fast gradients.
