Solid Phase Extraction and Accessory

Solid phase extraction (SPE) is a technique designed for rapid, selective sample preparation and purification prior to the chromatographic analysis (e.g. HPLC, GC, TLC). Analytical laboratories use solid phase extraction to concentrate and purify samples for analysis. In SPE, one or more analytes from a liquid sample are isolated by extracting, partitioning, and/or adsorbing onto a solid stationary phase. This sample preparation technique enables the extraction, cleanup and concentration of analytes prior to their quantification. SPE is usually used in the pharmaceutical, clinical and high-throughput diagnostic testing, forensic, environmental, and food/agrochemical industries. SPE extends the lifetime of chromatographic system, improves qualitative and quantitative analysis, and the demand placed on an analytical instrument is considerably lessened.
