UCT Flagship Sorbent Clean Screen® DAU cited in new Fentanyl/Opioids Analogs Paper
Since the introduction of Fentanyl as a legitimate medication, UCT has been at the forefront of assisting forensic toxicology facilities with the finest solid-phase extraction (SPE) sorbents and methodologies to extract and concentrate the drugs efficiently. With the recent emergence of newer potent analogs in the illicit community, UCT has expanded upon its existing sample preparation methods to include these novel, structurally similar derivatives. In a new paper authored by E.N.Shoff et al., published in Journal of Analytical Toxicology (doi: 10.1093/jat/bkx041), the determination of fentanyl analogs and other opioids in postmortem cases is thoroughly detailed employing Clean Screen® DAU solid-phase extraction cartridges as an integral part of this methodology.
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.

Clean Screen® DAU Used in Heroin-related Death Study Conducted in Jeddah, Saudi Arabia
Drug trends in some regions of the world are extensively studied while in other regions little to no research has been done. For example, countless studies have been performed in the United States of America while in the midst of its opioid epidemic. Meanwhile, in the Arabian Gulf region, only a few studies have been…
Clean Screen DAU Columns used in the analysis of ethylone related deaths
Researchers at the University of Florida, led by Dr. Bruce Goldberger, recently published an article in the Journal of Analytical Toxicology (DOI: 10.1093/jat/bkv053). The paper investigates nine postmortem cases in which ethylone, a synthetic cathinone, was identified.
The Fractionation of Aliphatic and Aromatic Hydrocarbons from a Petroleum Extract Is Messy Business – Extractable Petroleum Hydrocarbons
Most states have their method for extraction and fractionation, or they borrow one from another state. The sample is extracted with methylene chloride, solvent exchanged into n-hexane, and concentrated to a final volume. Fractionation is performed on a small 3 to 5g. silica gel column that has been pre-rinsed with n-hexane. The aliphatic hydrocarbons are…
