In the agricultural community, there are thousands of pesticides that could be potentially used to protect crops. In a recent paper published in Journal of Food and Agricultural Chemistry (J. Agric. Food Chem. (2017) 65, 473,493) by J.Wang et al., (Canadian Food Inspection Agency, Calgary, Canada), UCT’s Enviro Clean QuEChERS Pouches were used in conjunction with Enviro Clean 15mL dSPE centrifuge tubes for targeted screening of 448 pesticide residues in fruits and vegetables.

Separation Science has developed its fourth online eSeminar focusing on advances in forensics and toxicology. Taking place in two sessions, one each on 28 and 30 November 2017, this two-day online educational event will provide forensic scientists, toxicologists and those who work in laboratories within the forensic and toxicology industries with updates and guidance on the latest methods, protocols, processes and applications of chromatography, mass spectrometry and related techniques with key experts providing practical insights into their respective fields.

Our very own Forensic Technical Specialist, Tina Fanning, will be presenting in conjunction with an extensive panel of additional key experts in the field. The e-Seminar will comprise 7 presentations over 2 sessions featuring UCT’s platform topic, “A Modified QuEChERS Approach for the Extraction of Common Prescription and Illicit Drugs from Liver Prior to LC/MS-MS Analysis.” Click below to register for this exciting and informative event:

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.

Monolithic materials are versatile adsorbents widely employed in separation science, sample preparation and as supports for flow through applications (e.g. heterogeneous catalysis, ion-exchange, solid-phase extraction, etc). Interest around their preparation and applications has been steadily on the rise. In a recent paper published in Journal of Chromatography A ((2017) 498 46-55) by Patrizia Simonea et al., UCT’s specialty chemical N-trimethoxysilylpropyl)-polyethylenimine was employed in the production of capillary methacrylate-based monoliths. This process was executed by grafting from/to ƴ -ray polymerization on a tentacle-type reactive surface for the liquid chromatographic separations of small molecules and intact proteins.
