Natural Products Insider repots that 58 sports supplements have been tested using various chromatography methods, including GC., to test for steroids and stimulants.
Natural Products Insider repots that 58 sports supplements have been tested using various chromatography methods, including GC., to test for steroids and stimulants. The study was commissioned and funded by Informed-Choice and conducted by HFL Ltd., a Cambridge, England-based testing lab. Matrix effects prohibited having conclusive data for four samples via LC-MS and six with GC-MS. Of the 52 supplements tested via GC-MS, 13 contained small amounts of banned steroids; LCMS testing on 54 products revealed six contained banned stimulants. The non-peer-reviewed study did not state which supplements were tested, whether they were blinded, where they were purchased, or which products passed or failed.
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).
Pharmaceutical excipients, such as polyethylene glycol-based polymers, must be tested for the presence of ethylene oxide (EtO) and 1,4-dioxane as part of a safety assessment, according to USP Chapter <228>.
