有机氯农药系多组份的混合物,且它们之间互为异构体或代谢物,这给分离工作带来一定的困难.自从Thompson等报导用1.5％OV-17/1.95％QF-1涂制色谱柱以来,国内外推荐的方法或标准方法中普遍采用这种柱子进行有机氯农药的气相色谱分析。其结果,8个组份全分离需15至20分钟,而涂得差的柱子,难分离物质对还不能完全分离。前两年曾 Organochlorine pesticides are multi-component mixtures that are either isomers or metabolites with each other, which presents some difficulties in the separation process. Since Thompson et al. Reported that a 1.5% OV-17 / 1.95% QF-1 Since the chromatography column, this column is commonly used in the recommended methods or standard methods at home and abroad for the gas chromatographic analysis of organochlorine pesticides. As a result, 8 components of the full separation of 15 to 20 minutes, while poorly coated column, difficult to separate material pairs can not be completely separated. Two years ago
