[Abstract] Objective: To establish a method for simultaneous determination of 116 kinds of semi-pounds in water by gas chromatography/mass spectrometry with solid-phase extraction. Methods: Water sample was extracted on Cl8 solid phase column and eluted with dichloromethane & ethyl acetate then separated by GC with an DB-5 MS capillary column. The interest analyses were analyzed by gas chromatography/mass spectrometry used all scan mode. Selective ion masses were used in quantitative measurement. Results: Enable to easily and effectively separate and determinate 116 kinds of semi-pounds in water. In this
