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.
Gulf Coast Conference: Increasing Density and Viscosity Throughput with Difficult Samples
October 19th 2023Daniel Wolbrecht, senior technical sales consultant at Anton Paar, held a workshop at the Gulf Coast Conference in Galveston, Texas, focusing on how heated autosampler units can help analyze difficult samples.
