Total Quality Approach to all Aspects of Design, Manufacturing and Testing Each HPLC column and analytical cartridge from Higgins Analytical is evaluated by a computerized performance test prior to receiving a quality control approval. This testing protocol involves a highly accurate statistical moments determination of the column s performance characteristics. These sensitive peak shape and column efficiency measurements can only be made by computerized data logging methods. Product Traceability The test data for these serialized columns include sorbent properties and lot number as well as complete description of the test conditions. The instructions and other product information are detailed on the back of the test chromatogram. retrieve comprehensive quality control information and routinely apply it to our statistical process control activities. This commitment to quality manufacturing and comprehensive record keeping permits us to produce replacement Certificates of Analysis when requested by laboratories complying with their internal GLP needs. And, most importantly, we are able to assist customers during the lengthy process beginning with method development and optimization to validation and NDA filing by providing comprehensive serial number, manufacturing date, sorbent lot, and performance data for every column they ever purchased. Expert Manufacturing and State-of-the-Art Equipment Much of Higgins Analytical s staff has Comprehensive Record Keeping and Statistical Quality Control Raw digital test data is automatically archived for every column and analytical cartridge we manufacture. As a result, it is a simple matter for us to Higgins Analytical develops and manufactures a wide range of stainless steel and PEEK (polyetheretherketone) High Performance Liquid Chromatography (HPLC) columns and cartridges. These unique offerings address many needs of chromatographers desiring fast analysis times, efficient system and column protection, and chemical inertness. Special application areas include LC/MS, combinatorial chemistry, column switching techniques, in-line filtration, and guard column requirements. Products are supplied and supported worldwide by a network of responsive distributors. We are a quality-oriented chromatography company dedicated to providing performance products, expert support, and rapid delivery to research and quality control laboratories worldwide. been involved with the chemical separations business for over 20 years. By focusing this expertise exclusively on the separations consumables business, high quality products as well as high quality processes are assured. For example, our chemical engineer has developed solvent purification equipment and procedures that address all of the solvent requirements for production and quality control. Not only does this investment permit us to use the highest purity solvents available, it also eliminates much of the expensive and environment-polluting solvent disposal practice characteristically found in today s chemical industry.

Quality Design, Quality Manufacturing, Quality Control Computer Aided Drawings and Numerical Control Machinery Key to reinforcing our ability to provide the highest performance-to-price ratio products available in the separations consumables industry has been our investment in computer aided design (CAD) techequipment that minimize the health risks to us, and we have completely eliminated the use of ozone-depleting solvents. Since our plant is located on the edge of San Francisco Bay s picturesque wet-lands (home of the Thamnophis sirtalis tetrataenia - the endangered San Francisco gater snake, and venue for some of the best wind surfing in the world), we have taken extra measures to Our unique and highly automated column packing equipment is based on a closed, continuous flow system employing recoverable, unreactive, and safe fluids. And the best part about it is that it enables Higgins Analytical to manufacture a wide variety of HPLC columns with unrivaled efficiency. Concern for more than just the Green in our logo Our policy is to provide the highest performance available, so we put a tremendous amount of effort into assuring the quality of our products. We also place a great deal of attention on how we impact the environment. Just as our solvent purification practices have minimized our solvent consumption and waste disposal needs, the processes we have developed use materials and insure that our processes and products are environmentally sound. We are very proud of our compliance record with the local air quality, fire, and hazardous material regulatory agency requirements. Hardware Designed for Optimum Performance and Service Life High efficiencies and negligible extra-column effects are a certainty because Higgins Analytical columns use high quality PEEK and titanium frits that are only 0.75mm thick. Frit porosity also plays an important role in HPLC column design. Many manufacturers use 2µm porosity frits with their 5µm sorbents making high sensitivity work problematic since even the best particlesized 5µm materials can have 1% or more of sub 2µm material. These minute particles can pass through the frit and into the detector causing spiking and baseline noise. The column outlet fittings on Higgins Analytical columns have 0.5µm frits making them suitable for even the most sensitive detection Column labels are easy to read, impervious to solvent spills and temperature changes, and they do not dangle awkwardly from the column. Flow direction is clearly indicated.

CLIPEUS - A Small Shield Virgil s Aeneid gave us a sanguine account of the problems encountered when working without a Clipeus a small shield popularized by the Romans. While arguably a less painful experience, chromatographers 2,000 years later still struggle when they work with inadequately shielded HPLC columns that are the by product of flawed end-capping technology. Higgins Analytical places a great deal of emphasis on effective silanol end-capping techniques. The bulky size and secondary chemical functionality of the end-capping moiety on TARGA (a large shield) HPLC columns and cartridges make them popular choices for researchers developing powerful LC/MS techniques or chromatographers doing routine analysis of difficult polar compounds. CLIPEUS - A Small Shield for a Big Job Phases C8, C18, Cyano, Phenyl Particle Sizes 4.5µm Pore Size 120Å Pore Volume 0.8mL/gm Surface Area 330m 2 /gm %Carbon C18 = 18% (w/w) Phase type Extremely well end-capped monofunctional phases Silica Class Type B Hardware Stainless steel and PEEK columns and cartridges: Nanobore columns Page 6 Microbore columns Page 6 Analytical and Narrowbore columns Page 7 Semi-Prep and Prep Columns Page 7 Cartridge columns - Analytical Page 8 Cartridge Columns - LC/MS Page 8 High Speed 10mm Semi-Prep cartridges Page 9 Prep Guard Cartridges Page 9 Analytical Guard Cartridges Page 9 Narrowbore guards and LC/MS Cartridges Page 9 Our CLIPEUS columns are based on the same ultra-pure, Type B silica gel we use for our TARGA products, but the end capping is done with the more traditional methodology employing TMS, a small molecule; hence CLIPEUS - a small shield. CLIPEUS columns have Higgins Analytical s characteristically high lot-to-lot reproducibility because our carefully controlled reaction of monofunctional silanes can be driven to completion in a reproducible manner. This unbuffered Pyridine and Phenol chromatogram illustrates the absence of any undesirable solute/silanol interaction on a CLIPEUS C18 HPLC Column. Applications The high purity base silica and thoroughly end capped bonded phases insure that CLIPEUS columns and cartridges will perform well in demanding situations where many other column brands fail. Even polar compounds elute as sharp and symmetrical peaks permitting surprisingly short columns to be used for high speed analysis. In addition to C8 and C18 phases, CLIPEUS columns are available with phenyl or cyano functionality. CLIPEUS C18 5µm 150x4.6mm 40% MeOH/water (unbuffered) 1mL/min, 25ºC, 254nm P/N HC185-CS1546

CLIPEUS CLIPEUS Offers a Wide Range of Hydrophobicity The highly pure silica backbone and the thorough end-capping process that are characteristics of CLIPEUS HPLC columns enable a wide choice of column selectivity without compromising chromatographic performance. Not only do the columns with relatively small cyano and phenyl functional groups perform as efficiently as do the longer chain C8 and C18 versions of CLIPEUS, they also produce symmetrical peaks for acidic and basic analytes. This is usually not the case for these types of columns from most HPLC column manufacturers. The four CLIPEUS chemistry offerings and the wide variety of column and cartridge formats, with internal diameters ranging more than two orders of magnitude, present a powerful selection to a chromatographer desiring to optimize a difficult separation or to maximize the speed of a high throughput application.

HAISIL 100 - the Separations Work Horse The 100Å pore size, monomeric bonded phase, and very high performance make HAISIL 100 an ideal choice for separations ranging from small molecules such as carbamate Carbamate Pesticide Analysis on a 250x4.6mm HAISIL 100 Column pesticides and pharmaceutical drugs to synthetic oligonucleotides and small peptides. High efficiency, symmetrical peaks, and long column life is characteristic not only of the C8 and C18 reverse phase columns, but the normal phase silica columns as well.

The HAISIL 100 column and cartridge efficiencies are unrivaled yet they represent one of the most economical product lines in the market today. In formats ranging from 0.17 to 20mm ID and from 20 to 250mm in length, HAISIL 100 is the sorbent we use to drive our competition crazy whenever challenged to an efficiency bake-off. 250x4.6mm HAISIL 100 5µm columns routinely produce around 100,000 plates/meter in our QC lab. Note that our column efficiencies are calculated by statistical moments - not an approximate peak-width method! While this performance is more than adequate for most requirements, HAISIL 100 3mm is also available. Typical Test Chromatogram for a 3µm 150x3.0mm HAISIL 100 Column The typical test chromatogram on the Certificate of Analysis pictured below illustrates that HAISIL 100 C18 3µm columns have the same near theoretical reduced plate height and perfect symmetry that is characteristic of their 5µm counterparts.

HAISIL 100 1 Hormone Analogs LH-RH (Luteinizing Hormone - Releasing Hormone) Analogs are used for the inhibition of gonadal steroid production. An important application area is in the treatment of prostate cancer. Conditions HAISIL 100 C18 5µm 150x4.6mm Solvent A: Phosphoric acid, ammonium sulfate aqueous buffer Solvent B: Acetonitrile.

Besides good Alkaloids A Peruvian vine named Una de Gato (Uncaria tomentosa) and commonly referred to as Cat s Claw, has become a popular natural product source for herbal remedies. Enthusiasts claim the oxindole alkaloid extracts to be effective in the treatment of a wide range of digestive and circulatory diseases as well as Alkaloids from Cat s Claw analyzed on a HAISIL 100 C18 column P/N HS2546-HM185 other afflictions ranging from cancer to arthritis. Reputable providers of such phytochemical containing formulations carefully assay the alkaloid content of the extracts and formulations. The chromatogram above illustrates baseline resolution of Cat s Claw bark extracts containing isopteropodine, pteropodine, mitraphylline, isomitraphylline, ryncophylline and isorynchophylline. Kinetic Measurements in Disease Research Researchers at the University of California, Santa Cruz have recently published a novel HPLC method that yields baseline separation of per-deuterated and protonated lipoxygenases. The striking ability of a 250x4.6mm HAISIL 100 C18 column to resolve these two very similar compounds is enabling researchers to study large competitive kinetic isotope effects in Human 15-lipoxygenase catalysis. Protio/per-deutero ratio data obtained by this HPLC method agreed within experimental error of data obtained by ES-MS. The elucidation of these mechanisms is noteworthy because of the increasing role human lipoxygenases are playing in inflammatory diseases and cancer growth regulation. Enzymatic Reaction Mixtures of Human 15-lipoxygenase HAISIL 100 C18 250x4.6mm 74.9% MeOH, 25% water, 0.1%HoAC 1mL/min, 234nm P/N HS2546-HM185 PICOTAG Amino Acid Analysis linearity and column lifetime, the 150x4.6mm column yields very efficient amino acid analysis as shown in the chromatogram above (P/N HS1546-HM185). Why do HPLC columns plug up? A large percentage of HPLC columns die because the back pressure builds up. Most chromatographers (and many column manufacturers) believe this is because the inlet frit plugs up with particles. Actually, it is usually the packed-bed that becomes plugged by smaller than 1µm particles that pass through in-line filters and the 2µm inlet frit. 5µm Silica Gel Particle See pages 34-0.75µm Extra-Particle Flow Path

HAISIL 300 Wide Pore Columns Higgins Analytical's HAISIL 300 C4, C8 and C18 columns are popular alternatives for biomolecule analysis where larger pore diameters often enhance separations. High efficiencies, long column life, and extremely symmetrical peaks are characteristics of HAISIL 300 columns that range in size of 20mm - 250mm in length. 150µm - 20mm Internal Diameters Higgins Analytical's reputation for manufacturing efficient and robust columns now ranges from 150µm to 20mm internal diameter. The sub 1mm ALGO Series, meaning "a sharp needle," appropriately describes the peaks obtained from HAISIL 300 - for Biomolecules Phases C4, C8, and C18 Particle Sizes 5 and 10µm Pore Size 300Å Pore Volume 0.7mL/gm Surface Area 80m 2 /gm %Carbon (w/w) C4 = 3%, C8 = 4%, C18 = 6% Phase type Monofunctional and fully endcapped Silica Class Type A Hardware Stainless steel and PEEK columns and cartridges Applications HAISIL 300 columns and cartridges are ideal for biomolecule separations such as peptides and small proteins. Optimized phase bonding and column packing techniques assure unsurpassed performance and column-to-hcolumn reproducibility in comparison to other so-hcalled wide pore reverse phase columns offered by other manufacturers. Short cartridge columns are economical and are ideally suited for LC/MS applications. The column and cartridge offering ranges from 150µm to 20mm I.D. which means that bioseparations can be optimized by selecting a format that best fits your analytical requirements. Peptide Standards separated on a 250x1.0mm column (HW185-HS2501) with an efficiency that permits collection of 10µL peaks Higgins Analytical's high performance microbore HPLC columns. We're so confident about our ALGO Series HAISIL 300 C18 5µm performance, we challenge anyone to manufacture a better one. Depending upon the type of information a protein chemist is seeking, the HPLC analysis of a complex digest can take 1 to 2 hours. The following

Small proteins, on the other hand can yield fewer fragments, and if only a "fingerprint" of a digest is required, high peak capacity columns can be a waste of time. column provides hundreds of runs without performance loss even under the aggressive 6ml/min flow conditions used in this example. Fast Analysis of a Complex Drug Delivery System Most pharmaceutical QC laboratories are faced with rapidly increasing demands for high throughput capability. A good example of one laboratory's approach to addressing a large number of samples for analysis on a daily basis is summarized below. This novel drug delivery system contains a small protein and other components that span an order of magnitude in molecular weight. All the identification of more than 10,000 peptides. These distinct peptides are bound to a major histocompatibility complex (MHC) molecule on tumor cells. Extraction of approximately 5x10 10 cells yield several nanomoles of a very complex peptide mixture. Several rounds of RP-HPLC with different organic modifiers on a 40x2.1mm PEEK cartridge column (HAISIL 300 C18 5µm, P/N: HK0421- HW185) are performed to fractionate the mixture into individual components. The chromatograms below illustrate how this technique is being used to narrow the search for the one peptide that marks a particular tumor cell as being diseased enabling it to be recognized by the immune cells. Fractionation of a Purified Tumor Cell Extract Peptides ranging from 100 fmol to 1pmol are collected in 40sec intervals during a 70min gradient from 0-60% MeCN with HFBA modifier.

HAISIL HL - High Load Columns Often, a chromatographer needs to support the high sample throughput demands of real-time process control or large volume production monitoring. When maximum selectivity, high efficiency, and fast analysis times are called for, HAISIL HL (high load) C18 is a good choice. The high surface area (300m 2 /gm) of the 100Å pore size silica used for HAISIL HL permits high weight/weight carbon loading yet the same desirable monomeric characteristics of our other HAISIL sorbents.

Unrivaled End Capping Technology Efforts to eliminate solute-silanol interactions have recently lead to big advancements in sorbent chemistry. While secondary effects can be vital for obtaining desired selectivity in some applications, they rarely help when polar amines are being analyzed. Targa HPLC columns are true to the Latin root of their name. TARGA, meaning shield, is precisely the effect the unique bonded phase has on the silica s silanol surface. Many HPLC column manufacturers illustrate the performance of their columns packed with inert, base deactivated, Type B silica bonded phases by the chromatographic behavior of polar compounds such as pyridine. Performance claims Unbuffered 20% MeCN/water A more revealing test for solute-silanol interaction is to use a mobile phase containing a relatively low amount of organic solvent and no additives or buffers. Compared to three popular HPLC columns whose manufacturers claim have a high degree of inertness, TARGA C18 exhibits very good efficiency and symmetry for pyridine.

Basic and acidic drugs and peptides can be chromatographed efficiently with little or no buffer. Targa columns are particularly well suited for LC/MS applications where acetic acid or formic acid can be substituted for TFA resulting in significant increase in signal. While TFA is not required, it does not preclude its use on TARGA columns. TARGA exhibits extremely fast equilibration kinetics from high to low organic phase compositions. It works well in in 1%/min acetonitrile gradient on a short 50x1.0mm TARGA C18 column. Both dilute buffer examples are characterized by sharp peaks and no tailing LC/MS without TFA Researchers have shown that Higgins Analytical s TARGA C8 and C18 phases have an extremely well protected silanol surface.

Unfortunately, most of these approaches introduce undesirable secondary effects that preclude their use with acidic or basic solutes unlike TARGA with its unique bonded phase. Trace Catecholamine Analysis In vivo microdialysis present a challenge to both instrumentation and column design, especially when depended upon as a tool for routine analysis.

HAIPEEK and HAISpeed Holders for Guard, Analytical, SemiPrep and Prep Cartridges Leak-free operation without wrenches Wide range of lengths available - 2, 4, 5, 10cm Wide range of I.D.s available - 2.1 to 20mm Inert construction - no oxidation or galling Can be used with either s.s. or PEEK cartridges Direct column connection for guard cartridges No special tools required to extract cartridge HAIPEEK and HAISpeed Holders for Cartridge Columns The family of convenient cartridge holders from Higgins Analytical provides leak-free operation without requiring any tools. Their inert and robust design insures that the HAIPEEK and HAISpeed holders will not oxidize and their threads will never gall. Proven Seal Design The Holder s basic seal design is also used in many of the components of Higgins Analytical s highly automated column manufacturing equipment. Conditions used in HPLC column production often exceed the 10,000PSI pressure used for testing the HAIPEEK holder. And keep in mind that all this is achieved without having to tighten the assembly with wrenches! Knuckle Breaking Advice from the Net A well meaning chromatographer recently advised readers of a popular technical bulletin board on the Internet that his solution to the common problem of leaky guard holders from some manufacturers was to,...tighten the nuts until you think you are going to strip them. They never leak that way. Obviously this person had not yet tried a Higgins Analytical HAIPEEK holder! Format Flexibility The HAIPEEK holders are compatible with Higgins Analytical s PEEK guard and analytical cartridges as well our stainless steel HAICART guard cartridges. In addition, the stainless steel cartridges from several other manufacturers can also be used in these unique holders. Most applications benefit from the HAIPEEK Guard Holder s convenient a HAIPEEK Guard cartridge is used as a very short analytical column for fast separations. It also allows you to substitute a sample injection valve s sample loop with a HAIPEEK Holder, allowing guard cartridges to be used for sample enrichment applications. HAISpeed10 - A new, very high performance 10mm I.D. Cartridge System High throughput requiements for combinatorial chemistry applications often call for 10mm I.D. columns. Higgins Analytical has developed a convenient cartridge system that offers an economical solution for demanding combinatorial and semipreprative needs. Eventhough a HAISpeed10 cartridge costs a fraction of conventional 10mm HPLC column of the same length, they have the same consistantly high performance of other Higgins Analytical columns. HAISpeed20 - Unique Protection for 20mm I.D. prep columns Prep is a dirty business, and expensive columns can be quickly destroyed by crude samples if proper precautions are not taken. Higgins Analytical s HAISpeed20 Prep Guard System provides effective column protection without compromising performance. In addition to an efficiently packed bed which retains strongly absorbing junk that would change the selectivity of the prep column, these unique guard cartridges have 0.5µm frits that remove particulate contaminants as well. DO NOT USE HAISpeed HOLD- ERS FOR SFC and/or SFE APPLI- CATIONS! The HAISpeed10 and HAISpeed20 cartridge holders are rated for use up

Cartridge Holders 3 ability to connect directly to the HPLC column. A HAIPEEK Guard Holder having female fittings on both ends is also available, however. This symmetrical version (P/N HK-GUARD-FF) is called for when Heat Transfer Characteristics The thermal conductivity of the plastic materials in Higgins Analytical s cartridge holders (~0.15 BTU/(hr)(ft 2 )(ºF/ft) is one to two orders of magnitude smaller than aluminum (113) and stainless steel (~1,000) commonly used in other manufacturer s cartridge holders. Thermal equilibration rate measurements were made to determine how these differences in thermal conductivity would effect re-equilibration time after a temperature change. Experimental Results Relative temperature equilibration times for a Brownlee MPLC Holder and a Higgins HAIPEEK holder were determined chromatographically. A 40x3.2mm HAISIL 100 C18 5mm cartridge (P/N HM185- HF0432) was used for the analysis of fluorene in a 70% acetonitrile/water mobile phase at 420mL/min in both holder types. After determining the analyte s retention time at room temperature (21.7ºC), the assembly was placed in a forced air oven set to 35ºC. Retention time measurements were made at approximately two minute intervals until a steady state was reached. The figure to the right shows that rates for both holders were very similar, with equilibration being reached in a little less than 10 minutes. Notes Retention time precision was approximately + 0.02 minutes for these data. Oven temperature was measured to 0.1ºC. Oven temperature was 35.9ºC during the Higgins holder experiment. Temperature was 35.0ºC during the Brownlee holder experiment.

A simple, yet effective, means of protection is to place a filter in the flow path between the sample injection valve and the HPLC column. While this technique is commonly used, it is also commonly plagued by leaky holders and significant performance loss. The Higgins Analytical HAIFILTER resolves all of these problems! Simplicity and Convenience The Higgins Analytical HAIFILTER provides efficient and leak-free inline filtration, yet it does not require any tools. To make it even more convenient, the HAIFILTER is designed to connect directly to the inlet fitting on the HPLC column, maximizing performance, and minimizing hardware. The 0.5µm porosity frits will remove much of the particulate contamination that is largely responsible for column pressure build up and plugging. The holder s inert construction, and the availability of PEEK and titanium as well as stainless steel frits, insures that the HAIFILTER can address all of your inline filtration needs. needs....an ideal solution for high performance, in-line filtration Low cost, yet effective column protection Direct column connection and symmetrical versions No tools required Leak free operation 0.5µm filters in stainless steel, titanium or PEEK Inert construction s threads won t oxidize or gall Two Convenient Formats HAIFILTER is now available in two formats. The leak-free, finger-tight, and efficient performance are qualities of the HAIFILTER that have made it a popular product, replacing the competition s awkward and leaky alternatives in hundreds of laboratories worldwide. The direct- HConnect feature in the original design makes the HAIFILTER FM ideal for protecting HPLC columns while the symmetrical female thread fittings on each end of HAIFILTER FF provide unequaled flexibility to address your HPLC system s filtration requirements.

The HAIGUARD Holder and Guard- Disc System consists of a high pressure holder and a small disc of chromatographic sorbent contained in an inert polymer matrix. This compact package is easily connected directly to your analytical HPLC column providing an economical approach for enhancing column lifetime. Leak Free The HAIGUARD Holder s novel seal design assures leak-free operation. While the is rated at 4,000 PSI, the HAIGUARD Holder has undergone destructive testing at more than 10,000 PSI higher pressure than most instruments can even generate. While we don t recommend doing chromatography under conditions that would result in such high pressures, it is comforting to know that none of the HAIGUARD Holders tested experienced a leak. HAIGUARD Holder and Guard-Disc System Easy visual monitoring for contamination 0.2µm porosity Leak-free operation No tools required Inert construction - no oxidation or galling Economical - fraction of conventional guard cost 10x s the pore density of sintered filter materials Higgins Analytical provides chromatographers with a new concept in HPLC guard column technology. For the first time, users can protect their analytical HPLC column s from both chemical and particulate contamination with a device that does not interfere with the analytical column s chromatographic process. The ability to periodically inspect HAIGUARD for contamination is a further example of this product s uniqueness. No Tools Required One of the first things you will notice is that there is no knurling on the HAIGUARD Holder. Holder installation and Guard-Disc changes are accomplished without any tools. And, the reliable, leak-free performance, even under the challenging operating conditions used on some of today s modern HPLC columns, is achieved with only the slightest finger-tight torque during holder assembly. There is no more need to tear apart the lab looking for the 1/4 wrench that s never where you left it. Inert Construction The Holder is machined from a high

HAIGUARD 3 density PEEK extrusion. This provides not only a rugged design, but it also assures chemical inertness to commonly used HPLC solvents and buffer systems. This is especially important in applications where biocompatibility is a concern or electrochemical detection is involved. The HAIGUARD Holder and Guard-Disc System is the perfect complement to your biocompatible HPLC system and PEEK HPLC columns. Another advantage is that the PEEK threads will never gall or corrode as they do on many manufacturers guard holder designs. Visual Contamination Checks One of the biggest issues with guard column use is the uncertainty about when it should be changed. A recently published survey indicated that the typical user changes a guard column very few times throughout the analytical column s lifetime. One reason for this poor practice is that, except for back pressure build up, most indications of guard column failure come long after the analytical column has been damaged. With a Guard-Disc, a more rational approach can be taken. The Guard-Disc s unique design makes it the only HPLC column guard system that is capable of being visually inspected on a periodic basis. The Holder can be quickly opened to inspect the top surface of the disc for contamination, particles, or discoloration. Symmetrical Version for strength and flexibility. HAIGUARD is available in a symmetrical format with female fittings on each end. This version is a solution to situations where space constraints or instrument plumbing requirements don t call for the ability to directly couple the HAIGUARD to an HPLC column. Specifications Materials: The HAIGUARD Holder is made of PEEK (polyetherether ketone) and its components contain Teflon, 316 stainless steel, and titanium. The 1/16 tubing and ferrule are PEEK, and the finger-tight fitting are made of PEEK or acetal plastic. The Guard- Disc s sorbent is contained in a polymer matrix held in a PEEK ring assembly. Temperature and Pressure: Maximum recommended operating temperature is 80ºC. The maximum operating pressure is limited by the plastic bushing and ferrule which is approximately 4,000 PSI (275 BAR). Solvents: The Holder has very good chemical resistance to most commonly used HPLC solvents and buffer systems. DMSO, Me 2 Cl 2, and THF can cause PEEK to swell over a period of time, so they are not recommended for routine use. The Disc s characteristics are outlined in the table below. The C18B discs exhibit slightly chromatographic performance than the C18A type, but they should not be used with chlorinated solvents. Volume Variance: The Holder and Disc s contribution to an HPLC system s total system volume variance is about 20mL 2 at 200mL/min, so under isocratic conditions, some performance loss can be experienced with columns with I.D. s smaller than 4.6mm.

Part Numbering Scheme, Custom Services, and Acknowledgem We Violate the 80:20 Rule This catalog contains hundreds of parts and it would probably be no surprise to you if we pointed out that only about 20% of them are manufactured 80% of the time. But what you would not know is that another 20% of the products we manufacture are not even listed in this catalog! We stock tubing with a wide variety of internal diameters, and since we machine the columns and cartridges ourselves, custom length and I.D. columns are almost as easy for us to provide as are the standard sizes listed in this catalog. Since our part numbering system has an easy to understand pattern, customers routinely compose and order custom configurations. Easy to Understand Part Numbers Except for HAICART Guard Cartridges, all Higgins Analytical HPLC column product part numbers are based on a 2-4-4 character pattern. While we will not manufacture every combination and permutation devisable with this scheme, this page will serve as a guide to assist you in defining a product that you believe would better address your needs than one of the hundreds of formats we routinely manufacture. The two character prefix indicates sorbent and hardware type. Standard configurations are highlighted.
