The kind of purge and trap gas chromatography was independently researched. The instrument set automatic sampling, concentration, gas chromatographic separation detection functions in an organic whole, the volatile organic compounds in the water were analyzed with automatic on-line. The method was established by using this instrument for the simultaneous determination of 8 kinds of BETX volatile organic compounds in water. The experimental results showed that the method in 2~200 μg/mL range linear was good, the linear correlation coefficient was greater than 0. 999, and the detection limit was 0. 14 ~0. 39 ppb. The instrument performance was stable and reliable, the pre-treatment method was simply and quickly, and repeatability was good. It was very suitable for the determination of volatile organic compounds in surface water.
