[ SEP-PAK SOLID-PHASE EXTRACTION PRODUCTS ] SPE IS LIQUID CHROMATOGRAPHY Sep-Pak Cartridges use the code of liquid chromatography and a broad polarity spectrum of sorbents—including silica, acidic, neutral, and basic aluminas, Florisil™, and a selection of bonded silicas—to: Derivatize analytes using solid-phase reagents. Fractionate classes of compounds. Remove sample constituents that elute after the analytes of interest, or are strongly adsorbed on, LC columns. Remove sample constituents that coelute with an analyte of interest on LC columns. Desalt samples. Exchange solvents. Enrich sample...

ANATOMY OF A SEP-PAK CARTRIDGE [ Sep-Pak Classic ] A Precision Chromatographic Tool for Sample Enrichment and Purification Here are ten unique features that have set Sep-Pak Classic Cartridges apart from the competition and made them the most widely-referenced column liquid-solid extraction cartridges available today. Flexible inlet accepts male Luer tip for positive seal under pressure. Seamless body of virgin irradiation-crosslinked polyethylene has excellent solvent, stress-crack, and temperature extreme resistance. Tubing is specially selected and quality tested for very low level of UV-absorbing...

[ SEP-PAK SAMPLE EXTRACTION PRODUCTS ] [ SEP-PAK SOLID-PHASE EXTRACTION PRODUCTS ] No matter what your analyte of interest or sample type [chemical, environmental, food, or biological matrix], the wide variety of Sep-Pak sorbents and device formats [more than 200 combinations] and tens of thousands of published procedures make it very likely that you will find a Sep-Pak sample extraction product to meet your analytical challenge. General Elution Protocols There are two general strategies for isolating and cleaning up sample components of interest: 1. Adsorb matrix interferences while components...

[ SEP-PAK SOLID-PHASE EXTRACTION PRODUCTS ]] [ SEP-PAK SAMPLE EXTRACTION PRODUCTS Reversed-Phase Chromatography Because of the multiplicity of aqueous samples spanning a breadth of applications from environmental water to fruits and vegetables, from beverages to biological fluids, reversed-phase chromatography has become the predominant mode of SPE. To perform reversed-phase chromatography with SPE cartridges, use a gradient of strongly to weakly polar solvents [from weak to strong solvent elution strength] with a non-polar packing material. This procedure is illustrated in the figure here for...
