| 摘 要： | 丙草胺的含量分析多采用气相色谱法。本文采用气相色谱-质谱联用法（GC—MS）对丙草胺原药及其主要杂质进行分离鉴定，得到丙草胺及其7个杂质质谱图，分析这些质谱图，推断出各自的结构；并总结丙草胺质谱裂解规律及7个杂质的质谱特征，试验结果对控制丙草胺原药的杂质，提高产品质量，有参考意义。

| Abstract: | Pretilaehlor impurities have been taken into consideration of safey assessment of pestiedes.There were no articles for analysis of impurities in pretilachlor technical material to be found in present publieations.A GC-MS method,using DB-1 column （30m×0.32mm×0.25μm）, taking program temperature was developed to separate and analyze pretilachlor and 7 impurities in technical material.Using electron impact （EI） method, pretilaehlor and 7 impurities were identified and confirmed.The way of dissociation of pretilaehlor was discussed.Using GC-FID method,the content of pretilaehlor and 7 impurities were measured.The results showed a good repeatability. |
