Solid-phase extraction (SPE) is a widely used sample-preparation technique for the isolation of selected analytes, usually from a mobile phase (gas, fluidor liquid).The analytes are transferred to the solid phase where they are retained for the duration of the sampling process. The solid phase is then isolated from the sample and the analytes recovered by elution using a liquid or fluid, or by thermal desorption into thegas phase. SPE is now the most common sample purification technique in many areas of chemistry including environmental, pharmaceutical, clinical, food and industrial chemistry sectors.


Clovertech's QuEChERS

QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe), a sample preparation method proposed by Michelangelo Anastassiades and co-workers in 2003, has been adopted as official procedures for multiresiduals pesticide monitoring in Europe, the U.S. and China.
