摘　　要：本文介绍了用液上空间法气相色谱对仗水申痕量的挥发性卤代烃（氯仿、四氯甲烷）进行测定，对气相色谱用平衡管进行了改进，使用耐针刺硅橡胶及特制铜螺丝密封，具有不受非卤代挥发性化合物干扰、检测灵敏度高的优点。采用该方法可以对水样中痕量的氯仿、四氯甲烷进行测定，结果良好。Determination of trace volatile halogenated hydrocarbon (CCl4. CHCl3 ) in water by staticheadspace gas chromatography was investigated in this paper. Equalization tube for gas chromatography was improved. This methed for determination of CHCl3 and CCl4. has low detectionlimits and no interference of other volatile species. The trace CHCl3 and CCl4 in water was effectively detected by this methods.
