| 摘 要： | 研究了气相色谱内标法代替常规的标准工作曲线法测定偏二甲肼纯度（ＵＤＭＨ）。用内标与偏二甲肼混合样品，避免了微量进样不准确的缺陷。结果表明，该方法相对标准偏差接近于１％，回收率大于９８．０％。

| Abstract: | Gas chromatographic internal standard method was considered to determine purity for 1,1-dimethylhydrine(UDMH)instead of the standard working curve method. Weakness of trace impouring imprecisely was avoided by mixing UDMH and internal standard solution. The results show that relative standard deviation approaches 1% and the rate of collection is more than 98.0%. |
