UCT Clean Screen® DAU Cited in Novel Fentalogs Article

Methoxyacetylfentanyl and cyclopropylfentanyl are two of the newest illicit opioids that are infiltrating the heroin market. They both have been reported by the Drug Enforcement Administration in their third quarter report of 2017 to have been chemically identified seven and five times, respectively. In a recent paper authored by Melissa F. Fogarty et al., published in Journal of Analytical Toxicology (doi: 10.1093/jat/bky035), an analytical method was developed and validated to extract fentalogs from whole blood samples using UCT’s Clean Screen ® DAU. The method used LC-MS/MS for the quantitation of fentanyl, norfentanyl and 17 fentanyl analogs.

UCT QuEChERS Used for Analysis of Herbicide in Infant Formula

Haloxyfop is a selective herbicide that is used to protect crops such as potatoes and carrots against persistent grasses. In a recent paper authored by Urairat Koesukwiwat et al., (Analytical and Bioanalytical Chemistry https://doi.org/10.1007/s0021), the authors developed and validated a simple method for total haloxyfop analysis in infant formula and related ingredient matrices using UCT’s QuEChERS and liquid chromatography-tandem mass spectrometry (LC-MS/MS).

UCT QuEChERS Extraction Salts Cited In PFASs Study

Per- and polyfluoroalkyl substances (PFASs) are widely used in the manufacturing of various industrial and consumer products including nonstick food packaging, stain repellents and aqueous film-forming foams. In a recent paper published in Chemosphere ( (2018) 199 168-173) by Adcharee Karnjanapiboonwong et al., UCT’s QuEChERS extraction salts (4,000 mg MgSO4/1,000 mg NaCl) were employed to extract PFAS and other carboxylic acid compounds from earthworms. This was the first study on earthworms in PFAS-spiked soil at background concentrations. It was found that PFASs can be detected in earthworms even in the 0.1 mg kg1 soil treatment after 21-day exposure.
