摘要:综述了含硫恶臭物质的气相色谱分析方法。详细介绍了目前分析含硫恶臭物质常用的采样及预处理方式、色谱柱和检测器,对不同的采样及预处理方式进行了比较。在预处理方面,可选择FTFE气袋、硅烷化苏玛罐采样,通过三级冷阱预浓缩后进样;或者采用Hayesep N、Tenax TA等吸附剂采样,热脱附进样。在分离方面,非极性柱、中极性柱可同时分离多种物质,应用范围较广;专用色谱柱有更好的分离效果。在检测方面,硫化学发光检测器(SCD)对含硫化合物有更高的选择性,线性关系好,检出限低,全二维气相色谱和飞行时间质谱联用具有更好的检测效果,但成本较高,操作复杂,难以推广。最后展望了未来的研究方向,为进一步优化分析方法提供参考。  
Abstract:The analysis methods of sulfur-containing malodorous substances by gas chromatography were reviewed. The sampling and pretreatment methods, chromatographic columns and detectors commonly used in the analysis of sulfur containing malodorous substances were introduced in detail, and different sampling and pretreatment methods were compared. In terms of pretreatment, FTFE sampling bag and silanized Summa canister can be selected, and the sample can be pre-concentrated through a three-stage cold trap; adsorbents such as Hayesep N and Tenax TA can also be used for sampling and can be injected by thermal desorption. In terms of separation, non-polar column and mid-polar column can separate multiple substances at the same time, which has a wide range of applications; special chromatographic columns had better separation effects. In terms of detection, Sulfur chemiluminescence detector(SCD) had higher selectivity for sulfur compounds, good linear relationship and low detection limit. The combination of comprehensive two-dimensional gas chromatography and time-of-flight mass spectrometry had better results of assessment, but the cost was higher and the operation was too complex difficult to promote. Finally, the future research direction was prospected, and a reference for further optimization of analysis methods was provided.
