利用气相色谱 -质谱联用仪对溴苯腈除草剂所含杂质进行了研究 ,确定了其超过 0 .1%的杂质 ,并通过保留时间再确认进一步证实了所推断地杂质结构 ,同时建立了气相色谱内标定量分析方法 ,得到了满意的结果。
The impurities contained in the bromoxynil herbicides were studied by gas chromatography-mass spectrometry (GC-MS), and more than 0.1% of the impurities were identified. The confirmed impurity structures were further confirmed by retention time confirmation. At the same time, Gas chromatography internal standard quantitative analysis method, and obtained satisfactory results.
