UCT would like to extend a special thanks to all of this year’s attendees at NACRW who paid visit to the booth and/or attended our sponsored lunch and learn focused on veterinary drug residue analysis. This year was a great success and we are excited about the new and improved products and solutions that we were able to feature and demonstrate.

UCT Inc., is well-known for its commitment to support in the area of environmental analytical research. In a recent paper published in Science of The Total Environment by J-H Lee and J-H Oh ((2016) 556: 330-337), UCT’s Enviro-Clean 521 cartridges were used to extract nitrosoamines from water samples originating in sewerage water plants.
Analysis of umbilical cord samples offers forensic toxicologists a method for evaluating maternal drug intake patterns. These matrices may be an uncommon sample for many laboratories, but for those that are tasked with the challenge, solid phase extraction offers the most efficient methodology for the analysis of said compounds.
In recent paper authored by Amy Alexander et al., in Journal of Analytical Toxicology (doi: 10.1093/jat/bky009), UCT’s flagship sorbent Clean Screen®DAU (CSDAU020) was employed to analyze samples of umbilical cord taken from two monozygotic twins. It was found that the umbilical cord from newborn #1 was positive for hydromorphone only (1.06 ng/g), and the umbilical cord from newborn #2 was positive for hydromorphone (0.81 ng/g) and benzoylecgonine (5.41 ng/g).
With concerns over the household use of pyrethroid pesticides for mosquito control, researchers in Thailand have developed a validated method for analyzing cis/trans-permethrinic acid in powdered milk. Pyrethroids are naturally occurring pesticides that are synthesized to manufacture mosquito coils and sprays for home use. These pesticides can bioaccumulate in women’s bodies and be excreted in…
One of the issues that face forensic toxicologists is the analysis of chiral drugs especially within the amphetamine type substances (ATS). In a recent paper by I. Shu et al., published in the prestigious Journal of Chromatography B ((2016) 1028:145), methamphetamine was extracted using UCT’s flagship sorbent Clean Screen® DAU from hair samples. By executing an efficient sample clean-up and concentrating the extract, it allowed for the detection of the analytes in question at the concentrations normally encountered in a hair-based matrix.
Gallium-68 (68Ga, t1/2 ¼ 67.8 min) owns great potential in nuclear medicine being extensively used in labelling of biomolecules like somatostatin and PSMA inhibitor analogues. 68Ga decay to stable Zinc-68 (68Zn) nuclide via electron capture (11%) and positron decay (89%) and is generally produced via 68Ge/68Ga generators. Although this approach is widely used, the generators…
Per- and polyfluoroalkyl substances (PFASs) are a diverse group of synthetic organofluorine compounds that have been widely used in industrial applications and consumer products such as non-stick cookware, food packaging, fire-fighting foams, carpeting, apparels and metal plating. PFASs are persistent in the environment and are extremely resistant to degradation due to heat, acids or bases….
