Weed Killer Analyzed Using Molecularly Imprinted Polymer
A research group from BRGM (Orleans, France) and Ecole Superieure de Physique et de Chimie Industrielles (Paris, France) used terbutylazine molecularly imprinted polymers following a pressurized liquid extraction step to remove interfering compounds from soil extracts containing the herbicide atrazine.
A research group from BRGM (Orleans, France) and Ecole Superieure de Physique et de Chimie Industrielles (Paris, France) used terbutylazine molecularly imprinted polymers following a pressurized liquid extraction step to remove interfering compounds from soil extracts containing the herbicide atrazine. The soil samples were taken from the Brevilles watershed. Atrazine, desethyl-atrazine, and desisopropyl-atrazine were the analytes of interest in the study. The final analysis after the cleanup steps was obtained using reversed-phase liquid chromatography coupled with ion-trap tandem mass spectrometry. According to their report, the total mass in the top 60 cm of soil was estimated at containing 1.4 , 0.52, and 0.25 kg of atrazine, desethyl-atrazine, and desisopropyl-atrazine, respectively.

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).
