摘要
利用气相色谱(配火焰光度检测器)对二硫化碳(CS_2)、甲硫醇(CH_3CH)、甲硫醚(DMS)和二甲二硫醚(DMDS)4种含硫物质进行了分析检测,着重讨论了气相色谱仪的各项参数对几种含硫物质响应和分离效果的影响。结果表明:该分析对含硫气体的最小检测浓度达到ppb级。在各项参数中,色谱柱温度和N_2压力对各含硫物质响应和分离度影响最大,汽化室和检测器温度及空气压力对它们的影响相对较小。
In this paper, gas chromatography-flame photometric detector analyses on several volatile sulfur compounds gases, such as CS2, CH3SH, DMS and DMDS were discussed. The effect of several parameters of gas chromato-graph on sulfur compounds responding area and separating degree was emphasized. The result showed that the minimum detecting concentration of sulfur compounds was up to ppb level. The influences of column temperature and N2 pressure on sulfur compounds responding area and degree were the best.
