【摘要】 介绍了不同极性毛细管色谱柱分离11种氯苯类化合物的方法,通过实验证明,随着色谱柱极性的增加,11种化合物的分离得到改善,采用DB-5和AC-20双柱定性可以避免各种氯代物的干扰,达到准确定性的目的。更多还原

【Abstract】 In this article,we introduced the method of separating chlorinated benzenes by different polarity capillary columns.The result showed that the separation of 11chlorinated benzenes was improved with increasing the polarity of capillary columns.The fused-silica capillary columns DB-5 and AC-20 were the best dual columns for separation of chlorinated benzenes which could give the better resolution and selectivity.更多还原
