摘要：采用配有毛细管柱和FPD检测器的气相色谱对石油天然气中所含的6种硫化物进行了定性定量分析,得到了各硫化物质量浓度与色谱响应峰高的关系式,比较了不同气体取样袋材质对分析结果的影响。结果表明,实验所用色谱柱能够实现对各硫化物的有效分离,FPD检测器对天然气中该6种硫化物响应峰高的自然对数与硫化物浓度的自然对数呈现良好的线性关系,相关系数在0.980以上。普通橡胶材质采样袋对有机硫化物的吸附作用明显,不宜采用。
Six sulfur compounds in high sour petroleum and natural gas were determined qualitatively and quantitatively using gas chromatography equipped with capillary column and FPD （Flame Photometric Detector）. The relationship between concentrations of sulfur compounds and response peak heights was obtained, and the effect of sample collection bag made of different materials on analytical results was investigated. The sulfur compounds mentioned above can be separated effectively with the capillary column. The natural logarithm of concentrations and response peak heights show good linear correlation with a correlation coefficient above 0. 980. The sample collection bag made of common rubber material is not suitable for the quantitative analysis because of its evident adsorption of organic sulfur compounds.
