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%。 A capillary of volatile carbon-containing compounds in high-purity anhydrous hydrazine samples was established and analyzed by gas chromatography. The qualitative and quantitative determination of the samples was carried out. The results showed that the recoveries of UDMH, ethanol and methyl hydrazine were in the range of 91.6% ~ 107.7%, and the average recoveries of volatile carbon-containing compounds were 101.1%. The relative standard deviations (RSDs) ) Were in the range of 1.7% -4.1%, and the relative standard deviation of volatile carbon-containing compounds was 3.0%.
