摘　　要：气相色谱法测定有机溶剂中水的含量,采用自制填充柱及热导池检测器,通过对不同有机溶剂的测定,优化了测试方法和条件。乙醇溶剂中水含量在1.0～9.0×102g/L范围内呈线性关系,相关系数R=0.9955,最低检测限为1.0×10-1g/L。方法简单、灵敏度高、重现性好。测定了油漆稀释剂、酒类等样品,得到满意测定结果。Determination of water in organic solvents by gas chromatography, the homemade packed-column and TCD were selected. The methods and conditions were studied for determination the water in different organic solvents. The linear range was （H2O） 1.0-9.0×10^2g/L in ethanol solvents （R=0.9955）. The detection limit was 1.0× 10^-1g/L. The method was simple, with high sensitivity, good reproducibility. The water in paint thinner samples and alcohol samples were detected with satisfactory results.
