Membrane-Assisted Cleanup of Biological Extracts

Researchers from the UFZ-Helmholtz Centre for Environmental Research (Leipzig, Germany) used an accelerated membrane-assisted cleanup technique for the analysis of organic compounds in lipid-rich biological samples. A Dionex (Sunnyvale, California) ASE device was used to automate the technique. Semipermeable low-density polyethylene membranes enabled recoveries greater than 70% for the organic compounds from the lipid-rich matrix. The technique provided a higher matrix removal capacity than gel permeation chromatography.
