Rapid Determination of 33 Volatile Organic Compounds in Water by Purge and Trap Gas Chromatography-mass Spectrometry
A method for rapid determination of 33 volatile organic compounds(VOCs)in water by purge and trap gas chromatography-mass spectrometry was established.The water samples were analyzed by selective ion scanning mode,and quantified by internal standard method.The results showed that the detection limit of 33 volatile organic compounds was 0.1～0.4 µ g/L,the relative standard deviation of the relative response factor of the calibration curve is 2.5％～16.8％,the recoveries of the samples at three concentration levels are 83.9％～1 18％,and the relative standard deviation is l.1％～9.0％.The method has low detection limit,good precision,and high recovery rate.33 volatile organic compounds were completely detected in about 18 minutes,greatly improving analysis efficiency.The method is suitable for the analysis of volatile organic compounds in water for large batches.
