以60～80目的GDX-102填充柱作为色谱柱，以高纯氦气作为载气，建立润滑油中微量水含量的气相色谱分析方法，探讨该方法对微量水分分析的线性相关性和准确性。实验表明，在选定的色谱条件下，可以对润滑油中微量水分进行快速、准确的测定；当润滑油水的质量分数为0.02％～0.1％时，气相色谱分析的相对误差小于5％，回收率为98.8％～104.9％，线性相关系数为0.9992。该方法可用于工业上在用润滑油微量水分的快速、准确测定。

A gas chromatographic method used in lubricating oil moisture content determination was established using GDX-102 packed column with the size 60~80 mesh as the gas chromatographic column,and the high purity helium as the carrier gas.The linear relationship and accuracy for moisture content in this method were examined.The experimental re-sults show that the method can be used for fast and accurate analysis of each lubricating oil sample.When the moisture content in lubricating oil is 0.02%~0.1%,the experimental relative error is below 5%,the recovery rate is 98.8%~104.9%,and the linear correlation coefficient is 0.999 2.Therefore,this method can be used in industrial online analysis.
