建立了用气相色谱仪和硫化学发光检测器检测高含硫天然气中硫化合物的方法。运用微流控制器解决了高浓度H2 S对检测器的污染以及对其他硫化合物测定的干扰问题，只需一种标准物质就可快速经济地完成高含硫天然气中多种硫化合物测定。该方法根据标准物质的保留时间完成多种硫化合物的定性，并用外标法定量。用该方法进行高含硫天然气样品测定，硫含量和色谱峰面积呈明显的线性关系，线性相关系数 r为0．9997。测定质量浓度为2 mg/m3以下的硫化合物时，测定结果的相对标准偏差小于6．1％；测定质量浓度为2 m g/m3以上的硫化合物时，测定结果的相对标准偏差小于2．2％，满足高含硫天然气的分析需要。

The method was established for determination of sulfur compounds in high sour natural gas by gas chromatography with sulfur chemiluminescent detector .The pollution to de-tector and interference from high concentration H 2 S has been solved by using micro flow control-ler .A fast and economical method has been established to detect several sulfides in sulfur-bearing natural gas with only one standard material .The qualitative analysis of sulfides was performed according to retention time of standard material and the quantitative analysis was performed on the basis of External Standard Method .The linear relationship between sulfur content and chro-matographic peak area is obvious with this method for testing high sulfur natural gas sample and the correlation coefficient r was 0 .999 7 .The relative standard deviation for sulfides under the concentration of 2 mg/m3 was less than 6 .1% ,and that of the sample with the concentration a-bove 2 mg/m3 was less than 2 .2% .The methods can completely meet the needs to analyze the high sulfur natural gas .
