Clean Screen XCEL I Used to Confirm Fentanyl Overdose in Italian Case Study
Fentanyl, a well-known synthetic opioid approximately 100 times more potent than morphine, continues to be a public health issue. In cases of a fentanyl overdose, it is difficult to determine the cause of death based on toxicological information alone due to the tolerance of habitual users and significant post-mortem redistribution. An Italian group published a…

XtrackT SPE column used in research work focused on doping control in horse racing
The major metabolite of Dopamine, 3-methoxytyramine (3-MT) is monitored in equine urine samples as an indicator of dopaminergic manipulation from Levodopa administration. Tyramine is a biogenic amine produced by decarboxylation of amino acid L-Tyrosine. Changes in the diet could alter the concentration of tyramine making it a potential biomarker for monitoring dopamine abuse. The goal…
Cannabidiol Extraction and Quantification from Gummies
Katherine Biggie, a graduate student from Bowling Green State University, has published an excellent thesis entitled “CANNABIDIOL EXTRACTION AND QUANTIFICATION: A COMPARISON OF FOUR SOLVENT BASED EXTRACTION METHODS IN GUMMY MATRICES.” Four extraction methods were compared to determine the ideal method to use with a gummy matrix. The four methods are acetonitrile soak, QuEChERS followed…
UCT Specialty Chemicals Cited in Cancer Study Article
In a recent paper authored by Xiaoying Wang published in Talanta ((2018) 187 179-187), UCT’s specialty chemicals Tetraethylorthosilicate (TEOS) and trimethoxysilylpropy-diethylenetriamine (DETA) were employed in the process to produce an electrochemiluminescence (ECL) biosensor for detection of CdkN2A/p16 anti-oncogene based on functional electrospun nanofibers and core-shell luminescent composite nanoparticles.
UCT QuEChERS Kits Cited in the Analysis of Asian Style Sauces
UCT is known around the world as the first company to commercialize the QuEChERS ((Quick, Easy, Cheap, Effective, Rugged, and Safe) approach and is proud to support facilities involved in food safety testing using this technique. In a new paper published in Journal of Agricultural and Food Chemistry (DOI: 10.1021/acs.jafc.6b05051) by S. Genualdi et al., (U.S. Food and Drug Administration, Maryland, USA) the simultaneous analysis of 3- monochloropropane-1,2-diol (3-MCPD) and 1,3 dichloropropane-2-ol (1,3-DCP) was executed in asian style sauces. In this report UCT’s extraction mylar pouches (AOAC Blend) which include 6 g MgSO4 with 1.5 g of sodium acetate and dSPE clean-up pouches containing 400 mg of PSA and 400 mg of C18 were employed to perform the QuEChERS extraction prior to analysis of 3-MCPD and 1,3-DCP. This new method utilized direct analysis of the extract without derivatization using gas chromatography-triple quadrupole mass spectrometry (GC-MS/MS). The developed method was applied to 60 genuine soy sauce samples to determine if concentrations have changed since the FDA limit was set in 2008.
