摘    要:
利用气相色谱(配火焰光度检测器,采用3mxφ2mm玻璃填充柱分离)对CS2和甲硫醚(DMS)两种含硫化合物进行了分离检测。该方法具有较高的灵敏度和良好的线性关系。结果表明:该分析对含硫气体的最小检测浓度在mg/m3级,在柱温为70℃,检测器温度为180℃,气化室温度为150℃,氮气流速为50mL/min时,CS2的回收率为98.66%,变异系数为2.12%;甲硫醚的回收率为98.66%,变异系数为1.56%。

关 键 词:CS2  甲硫醚  恶臭  气相色谱

Abstract:
Gas chromatography was used to analyze two volatile sulphur compounds gases as CS_2 and DMS, with higher sensitivity and linearity. Results showed that the minimum detecting concentration of sulphur compounds was up to mg/m~3 level. With the column temperature in 70℃, injector temperature in 180℃, detector temperature in 150℃, and N_2 flow rate at 50mL/min, the recovery of carbon disulfide was 98.66%, and relative standing deviation was 2.12%, while the recovery of dimethyl sulphide was 98.66%, and relative standing deviation was 1.56%.
Keywords:carbon disulfide  dimethyl sulfide  odorous gas  gas chromatography
