Mass Spectrometry Test for Sports Doping
Researchers at the University of Utah's (Salt Lake City) Sports Medicine Research and Testing Laboratory developed a test for testosterone and epitestosterone in urine that uses liquid chromatography with tandem mass spectrometry detection (LC-MS-MS).
Researchers at the University of Utah's (Salt Lake City) Sports Medicine Research and Testing Laboratory developed a test for testosterone and epitestosterone in urine that uses liquid chromatography with tandem mass spectrometry detection (LC-MS-MS). The test is designed to detect whether an athlete has used testosterone-boosting drugs. The analysis compares the ratio of testosterone to epitestosterone, which normally are present in approximately equal amounts. The new test provides 1-ng/mL sensitivity and enables analysts to determine the ratio with greater confidence.
Inside the Laboratory: The Richardson Group at the University of South Carolina
November 20th 2024In this edition of “Inside the Laboratory,” Susan Richardson of the University of South Carolina discusses her laboratory’s work with using electron ionization and chemical ionization with gas chromatography–mass spectrometry (GC–MS) to detect DBPs in complex environmental matrices, and how her work advances environmental analysis.

RAFA 2024 Highlights: Contemporary Food Contamination Analysis Using Chromatography
November 18th 2024A series of lectures focusing on emerging analytical techniques used to analyse food contamination took place on Wednesday 6 November 2024 at RAFA 2024 in Prague, Czech Republic. The session included new approaches for analysing per- and polyfluoroalkyl substances (PFAS), polychlorinated alkanes (PCAS), Mineral Oil Hydrocarbons (MOH), and short- and medium-chain chlorinated paraffins (SCCPs and MCCPs).
