UCT is proud to support Emerald Scientific’s 2017 annual conference which is devoted to the deep exploration and discussion of the science of cannabis, including analytical testing, extraction and infusion sciences, cultivation sciences, clinical applications, inter-lab comparison and proficiency testing, state regulations, industry standardization, and more. Please join us all week at BOOTH 132 to learn more about our latest product offerings including QuEChERS products and well-plates geared towards the analysis of cannabis and edible products, Selectra® HPLC columns, GC liners, Selectra-Sil® Dervatizing Reagents, and Ultra Flash® Flash Chromatography Purification offerings.
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…
Chemical protection of plants is necessary to maximize crop yields. Consequently, using pesticides can disrupt the concentrations of biochemical compounds in plants and reduce the availability of essential plant nutrients available to the human diet. Researchers at the Institute of Plant Protection – National Research Institute in Poland have recently published a paper showing how…

For many forensic toxicologists working with active drugs, the parent substrates may not be present in biological matrices, only the metabolites. From these metabolites, the parent drug may be assessed. This is typically performed by characterization of both the parent and metabolites. In a recent paper authored by Courtney Campbell et al., in Journal of Analytical Toxicology (doi: 10.1093/jat/bkx067), a validated method for the characterization of degradation products formed from selected phenothiazine drugs was employed utilizing solid-phase extraction (SPE) and UCT’s XCEL1 (130 mg in 48 well plate format).
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….
