ABSTRACT Purpose: To develop a simple and fast LC-MS/MS method for quantification of THC and THC-COOH in oral fluid. Methods: A solid phase extraction (SPE) method was developed on a Thermo Scientific™SOLAµ™ SAX 96-well plate to simultaneously extract THC and THC-COOH from oral fluid. Extracted compounds were separated on a reverse phase column chromatographically followed by … Solid Phase Extraction/SPE Guide : Waters Definiton of Solid-Phase Extraction. SPE is a sample preparation technology that uses solid particle, chromatographic packing material, usually contained in a cartridge type device, to chemically separate the different components of a sample. Samples are nearly always in the liquid state [although specialty applications may be run with some Solid Phase Extraction (SPE) | Agilent Choose from our wide selection of solid phase extraction (SPE) products for your sample preparation needs.
