毛细管-气相色谱法测定高纯级无水肼中挥发性含碳化合物的含量

摘要

A method for determination of volatile carbonaceous material in anhydrous hydrazine of high purity grade by capillary column-gas chromatography was developed, which was also applied to the qualitative and quantitative analysis of real samples. The results showed that the spiked recoveries of unsymmetrical dimethylhydrazine, ethanol and monomethyl hydrazine were all between 91.6%and 107.7%, the average recovery of volatile carbonaceous material was 101.1%;and relative standard deviations (RSDs) of three components were between 1.7%and 4.1%, the RSD of volatile carbonaceous material was 3.0%.%建立一种高纯级无水肼样品中挥发性含碳化合物的毛细管-气相色谱分析方法，并针对实际样品进行定性和定量测定。结果表明，偏二甲肼、乙醇和甲基肼的加标回收率均在91.6%～107.7%范围内，挥发性含碳化合物总平均回收率达到101.1%；3种物质的相对标准偏差（RSD）均在1.7%～4.1%范围内，挥发性含碳化合物的相对标准偏差为3.0%。
