Additional Information
Sep-Pak C18 3 cc Vac Cartridge, 200 mg Sorbent per Cartridge, 55-105 µm, 50/pk The Sep-Pak C18 3 cc Vac Cartridge is a powerful tool that helps you attain your solid phase extraction goals. It features a silica-based octadecyl bonded phase with strong hydrophobicity which is used to adsorb analytes of even weak hydrophobicity from aqueous solutions. Typical applications of this cartridge include drugs and their metabolites in serum, plasma or urine, desalting of peptides, trace organics in environmental water samples, and organic acids in beverages. This line of syringe-barrelled cartridges are designed for use with vacuum manifolds and automated SPE instruments. The convenient format and features of Sep-Pak cartridges overcome many of the procedural difficulties of traditional column liquid-solid extraction and allow the enormous benefits of solid phase extraction to be realized. Absorbent and packed bed quality, reproducibility, versatility, and ease of use are assured through intelligent design, production control, and quality testing. This cartridge helps you realize your full potential in solid phase extraction by using premium sorbent to ensure reproducibility. Every step of the production process is done in an ISO 9002 certified plant under stringent GLP and cGMP guidelines that ensure the quality of your lab equipment. Waters takes significant steps to make certain that the solid phase chemistry does not change between batches. Each batch of Sep-Pak cartridge stationary phase undergoes a variety of rigorous analytical checks and functional chromatographic testing to ensure that each application will perform identically on every batch of sorbent. The Sep-Pak C18 3 cc Vac Cartridges offer a wide variety of benefits including lower cost, greater recoveries, faster protocols, and much more. This cartridge is extremely cost effective due to reduced solvent consumption, lower reagent consumption, and less apparatus. Recoveries are increased by ensuring minimal sample transfer, and protocol speed is increased by reducing the number of steps involved in use. Sep-Pak C18 3 cc Vac Cartridges also ensure greater safety and accuracy by reducing exposure to toxic agents and ensuring that no cross contamination occurs. Additionally these cartridges ensure no emulsion problems, no need to transport samples to the lab, reduced harm to labile samples, and minimal glass breakage. This tool will enable you to attain top notch solid phase extraction performance in virtually every area imaginable. If you are looking to ensure the best performance from your vacuum manifolds and channel cartridge eluents effectively you may want to purchase our Long Needle Valve for Sep-Pak Device Vacuum Manifold, 20/pk.

FAQ
Why is sample preparation primer important? Recently advances in analytical instrumentation have shifted analyst jobs from assay measurements to sample preparation and data analysis. As the stringency of requirements for higher sensitivity, selectivity, accuracy, precision, and number of samples has increased dramatically, the corresponding advances in data collection and analysis have outpaced the traditional techniques of sample preparation.
