TL;DRAbstract

Based on Evaluation and Expression of Uncetainty in Measurement, the measurement results of epichlorohydrin in water samples by purge and trap-gas chromatography-mass spectrometry were collected and the measurement uncertainty was evaluated. The results indicated that the main factor were the prowess of making the standard curve, and the measurement result of epichlorohydrin in simulated water sample by purge and trap-gas chromatography-mass spectrometry was (78±21) μg/L.
