Abstract

The microwave energy produced in a cavity of the magnetron was used to extract chlorinated benzenes from water samples. This dynamic extraction method employs a stream of helium. Results were compared with those obtained by liquid‐liquid and the large volume extractions. The microwave extraction provides results that are comparable with those obtained using other techniques, while offering the advantages of speed. The preconcentration factors are approx. 1000 and corresponding detection limits for 1 liter of water are in the pg/L range, when determination of individual polychlorinated benzene congeners is performed using HRGC/MS/ selected ion monitoring.

## Abstract The microwave energy produced by a high intensity microwave oven was used to extract polychlorinated biphenyls (PCB) from water samples. This static method was compared with liquid‐liquid extraction to determine the optimum and limiting conditions in extraction processes. The sample siz
