Founded in 1986 in Horsham, PA, United Chemical Technologies, Inc. (UCT, Inc.) has grown from a manufacturer of solid phase extraction sorbents into a major competitor in the fields of specialty chemicals, chromatographic media and sample preparation products. UCT began with a novel technological idea for solid phase extraction (SPE): bond two different functional groups to a solid support material in order to create phases that are capable of extracting samples based on different chemical principles. The first product was our CLEAN SCREEN® DAU. This product incorporated an ion exchange functionality with a hydrophobic alkyl chain. This product was quickly adopted in analytical labs and is now the most widely used SPE material in the clinical and forensic industry for the clean extraction of biological matrices.
UCT Consumables Cited in Mephedrone Study
In a study published in Drug Testing and Analysis, J. Czerwinska et al., (doi: 10.1002/dta.2525), developed a liquid chromatography tandem mass spectrometry method using UCT’s Selectra® PFPP LC column for the simultaneous quantification of mephedrone and five of its phase I in human whole blood after extraction with UCT’s Xtrackt® solid phase extraction (SPE) columns. Mephedrone’s stability in whole blood has been previously investigated but this is the first-time stability of its metabolites has been assessed, indicating -20°C to be the recommended storage condition for all analytes.
