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 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 PSA Sorbent Cited in Sulfonamides and Trimethoprim Fish Analysis Paper

Tuesday, March 20th, 2018

Brazil is one of the largest veterinary markets in the world, and aquaculture, in particular fish farming, is the fastest growing sector of animal food production in the country. In fish farming, antimicrobials, including sulfonamides, are used for the treatment of bacterial diseases. Sulfonamides belong to an important group of synthetic antimicrobial agents that have been used in human and veterinary medicine for over 60 years. Recently, these drugs have been extensively employed in animals intended to produce food for human consumption.

In a recent paper authored by Katia Nunes et al., published in Journal of Analytical Methods in Chemistry (doi.org/10.1155/2018/4506754), a multiresidue method for detecting and quantifying sulfonamides (sulfapyridine, sulfamerazine, sulfathiazole, sulfamethazine, sulfadimethoxine, sulfamethoxazole, and sulfamethoxypyridazine) and trimethoprim in tilapia fillet (Oreochromis niloticus) was developed and validated using UCT's QuEChERS clean-up products in conjunction with liquid chromatography- mass spectrometry (LC-MS/MS).
