Abstract

This paper discusses the interfacing of continuous membrane extraction, pervaporation and on-line HPLC-UV detection into a total analytical system (TAS). Organics from a water sample were extracted into an organic solvent, and then concentrated via pervaporation prior to HPLC-UV detection. Factors affecting the system performance were studied. With optimized experimental parameters enrichment factors as high as 192 were obtained, the method detection limits were at low ng/mL levels, and the precisions were better than 5%.
