A traditional quartz tube and a method of injecting gas sample for determining the minim total sulphur in gas was improved,a additional tube for injecting gas sample was designed to directly insert into the area of combustion,gas sample was transported into the area of combustion by the use of the tube and gas sampler, without passing through the area of vaporization.Minim total sulphur content in gas was rapidly and precisely determined.%文章对传统的分析气体中总硫的石英管的结构和进样方法进行改进，在石英管中增加一根直接插入燃烧段的进样管线，通过该管线将气体样品由气体进样器直接送入燃烧段，不经过气化段，可快速准确分析气体中的微量总硫含量。该方法基线稳定、峰型对称、重复性好、准确度高、操作简单。
