| 摘 要： | 对气相色谱法检测无水肼中水含量过程的不确定度进行评定,系统分析检测过程中不确定度来源和各不确定度分量对分析结果的影响,通过对不确定度的分量进行分析和合成,可知标准溶液配制的过程、标准曲线的拟合和测量样品时的重复操作带来的不确定度分量是影响无水肼中水含量测定不确定度的主要来源.

| Abstract: | The uncertainty existing in the whole procedure of determining the water content in anhydrous hydrazine by gas chromatography was studied.The source of the uncertainty produced in the process of detection and influence of each component uncertainty are analyzed systematically.Each component of uncertainty was evaluated and synthesized.The results show that the uncertainty component produced by the repeat operation during the preparation of standard solution,fitting of standard curves and detection of sample is the major source which affects the uncertainty determination of the water content in anhydrous hydrazine.This work can provide the effective and credible data for the determination of water content in anhydrous hydrazine. |
