摘　　要：采用气相色谱/质谱(GC/MS)联用仪,测定柴油中元素硫含量的方法。该方法采用直接进样,完成一个样品分析只需20 min,最小检测量为4.5×10-11g。其线性范围宽可为0.01～100 mg/L,线性相关系数大于0.999 5;该方法精确度高,相对标准偏差<5%,回收率为93.0%～106.2%。与以往的其它元素硫分析方法相比,更简便、快速、灵敏,且无干扰。We determined content of sulfur in diesel oil with GC/MS.It only need 20 min to complete a samlpe analysis.Its least inspecting amount is 4.5× 10-11g.Compared with other methods,this method is easy,quick,sensitive and has no interference.Its linear range is 0.01～100 mg/L.Its linear correlation coefficient is bigger than 0.9995.Its relative standard deviation is below 5%.Its recover rate is 93.0%～106.2%.
