Solid Phase Extraction (SPE)

Solid phase extraction (SPE) is a technique designed for rapid, selective sample preparation and purification before the chromatographic analysis . Solid phase extractions (SPEs) are routinely utilized in the sample preparation for quantifying analytes in biological fluids like plasma and urine. In SPE, one or more analytes from a liquid sample are deserted by extracting, partitioning, and/or adsorbing onto a solid stationary phase
