Solid-Phase Extraction (SPE)

A sample preparation method that gathers analytes from solution onto a solid-phase substrate, followed by extraction or desorption of the analyte from the substrate via an appropriate solvent. There are a variety of solid materials that are used to selectively extract target analytes from a sample or remove the sample matrix. SPE is also used as a concentration technique or to change the solvent to one that is more amenable to the analysis. The solid phase material is placed in a variety of holders, from cartridges and disks, to being coated onto a fibre (SPME) or stir-bar (SBSE).
