SPE Cartridges

SPE is an increasingly useful sample preparation technique. It’s a method of sample preparation that concentrates and purifies analytes from solution by sorption onto a sorbent contained in either a disposable solid phase cartridge or a 96-well plate, followed by elution of the analyte with a solvent and reconstitution into a mobile phase that is appropriate for the instrumental method used for analysis.

SPE is divided into the following four categories, ion-exchange extraction, mixed mode, normal phase extraction and reversed phase extraction in the fields of agricultural and food, bio-analytical, environmental and forensic applications.
