The article uses large volume injection needle to do the injection ( Each needle has the amount of 10μL) and adopts gas chromatography -mass spectrometry to deter mine the five kinds of organochlorine compounds in sur-face water.Detection instrument's detection limit is between 0.11μg /L and 0.17μg /L,and the method's detection limit is between 0.0011μg /L and 0.0017μg /L.The separation effect,sensitivity,precision and accuracy all reach a high level.Compared with GB HJ699-2014,the article su mmarizes that this method is more suitable for the deter mination of trace levels of organochlorine compounds for the advantages of lower detection limit and less organic rea -gent's consumption .
