Solid Phase Extraction Products: The Quality You Require and the Performance You Demand

A solid phase extraction (SPE) brochure, containing product information and selection guides, is available from Supelco (USA). SPE is a form of step-wise chromatography designed to extract, partition, and/or adsorb one or more components from a liquid phase (sample) onto stationary phase (sorbent or resin). Using liquid chromatography principles to control selectivity, SPE provides the sample clean-up, recovery, and concentration necessary for accurate analysis. It has become the most powerful technique available for rapid and selective sample preparation (prep) prior to analytical chromatography. In addition, SPE extends a chromatography system’s lifetime, improves qualitative and quantitative analysis, and by changing an analyte of interest’s original matrix environment to a simpler matrix more suitable for subsequent analysis, the demand placed on an analytical instrument is considerably lessened.

The multitude of available phase chemistries can be packed into an array of hardware formats such as glass tubes, 96-well plates, preparative SPE Büchner funnels and dispersive SPE, and can be processed using dedicated vacuum manifold accessories.
