Description

Capillary GC/MS combined with purge and trap technique has been applied to analysis for traces of dichloroethyleneisomers (DCEs) in water. With the cryo-capillary interface mode, the detection limit was 0.01μg/l with 5ml sample size. Reproducibility ofselected ion monitoring (SIM) chromatographic peak areas were in the range of 4-7%for concentration of 1μg/l, but were 10% for 0.05μg/l concentrations. The SIM peakintensity ratios between monitor ions showed excellent reproducibilities. The resultsobtained with the cryo-column mode were also discussed and compared with those of the cryo-capillary interface mode.
