Spe Column

Sample preparation is one of the most important key steps for the entire analysis process, as over 60% of the entire analysis process time and over 30% of the analysis errors are from the sample preparation. Over the last twenty years, SPE has become the most powerful technique prior to analytical chromatography for the cleanup, purification, and concentration of samples from various matrices, including urine, blood, water, beverages, soil, and animal tissue.
Benefits of SPE:Switch sample matrices to forms more compatible with chromatographic analysesConcentrate analytes for increased sensitivityRemove interferences to simplify chromatography and improve quantitationProtect the analytical column from contaminantsCommon SPE Applications: Pharmaceutical compounds and metabolites in biological fluidsDrugs of abuse in biological fluidsEnvironmental pollutants in drinking and wastewaterPesticides and antibiotics in food/agricultural matricesDesalting of proteins and peptidesFractionation of lipidsWater and fat soluble vitaminsSPE ProductsPolymeric SPE: PS/DVB, BRP, P-SCX, P-SAX, P-WCX, P-WAXSilica based SPE: C18E(end-capped), C18, C8, Phenyl, CN, NH2, PSA, SCX.
