摘　　要：采用顶空进样-气相色谱方法,以纯化水作为稀释用溶剂,建立一种同时测定建筑用胶粘剂中苯系物和卤代烃的测定方法。通过优化顶空进样器条件,使用极性色谱柱对间二甲苯和对二甲苯进行分离。结果表明:卤代烃和苯系物检测线性相关系数高,检验精密度高;采用同一系统,在降低极性物质挥发后,分流进样,可以满足对苯系物和卤代烃的同时测定。To establish a method for the simultaneous determination of benzene and halogenated hydrocarbons in building adhesives. Headspace sampling-gas chromatography was used to purify water as a solvent for dilution, and the conditions of the headspace sampler were optimized. The polar chromatography column was used to separate meta-xylene and p-xylene. The results show that the linear regression coefficients of halogenated hydrocarbons and benzene series are high, and the test precision is high. Using the same system, after reducing the volatilization of polar substances, split injection can meet the simultaneous determination of benzene and halogenated hydrocarbons.
