Researchers from the Helmholtz Centre for Environmental Research (Leipzig, Germany) used the Chemcatcher aquatic passive sampling device to collect samples from a 1-day pulse contamination with the pesticide thiacloprid. The device consists of a sampler body and an Empore disk (3M, St. Paul, Minnesota) as the receiving phase. They examined a configuration without a diffusion-limiting membrane, which led to biofouling of the disk receiving phase. Use of a diffusion-limiting polyethersulfone membrane prevented the biofouling.
Dispersive Liquid-Liquid Microextraction: A Review and Roundup of Green Sample Prep Advancements
May 15th 2024The still relatively new technique has distinct advantages, but a few of those benefits make it incompatible with some of the currently accepted principles of green sample preparation.
