Solid phase extraction (SPE) is a technique designed for rapid, selective sample preparation and purification prior to chromatographic analysis. Using liquid chromatography principles to control selectivity, SPE provides the sample cleanup, recovery, and concentration necessary for accurate quantitative analysis.
The multitude of available phase chemistries can be packed into an array of hardware formats such as glass tubes, 96-well plates, and QuEChERS tubes (dispersive SPE), and can be processed using dedicated vacuum manifold accessories.
