摘　　要：采用顶空进样器在实验室模拟橡胶硫化条件,产生并收集硫化烟气,通过气相色谱-质谱联用技术对硫化烟气成分进行定性定量分析。对有标样的成分,采用外标法准确测定其含量;对于无标样的成分,选取与之最接近的同类结构标准物质作为标样进行半定量分析。该方法可以快速分析橡胶硫化烟气的成分及含量,具有良好的准确度和重复性。A headspace sampler was used to simulate rubber vulcanization in the laboratory to generate and collect vulcanization fume,and then the vulcanization fume was directly analyzed qualitatively and quantitatively using gas chromatography-mass spectrometry technology. For the components with commercial standard samples,the external standard method was used to accurately determine their contents,and for the components without commercial standard samples,the standard substances with the most similar structures were used as the external standard samples for their semi-quantitative analysis. This method could quickly determine rubber vulcanization fume compositions and their contents with good accuracy and repeatability.
