About Us

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 Clean Screen® EtG SPE Sorbent cited in Alcohol/Drugs Licensing Article

Monday, March 26th, 2018

Elena Lendoiro et al., published in Forensic Science International (/doi.org/10.1016/j.forsciint.2018.03.023) on the use of UCT’s Clean Screen® EtG solid phase extraction sorbent to determine the ethyl glucuronide (EtG) content of drivers suspected of alcohol/drugs driving cases under voluntary conditions. A validated analytical method for EtG was established which had a limit of quantification (LOQ) of 5 pg/mg of hair. It was found that 22 hair samples were positive for EtG where concentrations (20.7-1254.1pg/mg) were higher than the Society of Hair Testing (SoHT) cut-off for chronic alcohol consumption (≥30 pg EtG per mg of hair) in 21 cases.
