壬苯醇醚中二噁烷的限量检查方法

Limit Test of Dioxane in Nonoxinol

叙述了在壬苯醇醚样品中定量加入限量的二烷作为对照 ,以供试品中二烷峰面积的 2倍不得超过对照峰面积为判断标准的限量检验方法。本方法快速、准确、简便 ,测定结果与部颁法一致。

A GC method for the limit test of dioxane in nonoxinol was described. The limited content of dioxane was added quantitatively in nonoxinol as the reference standard. The two fold peak area of dioxane in the sample to be tested should not exceed the peak area of dioxane in the controlled sample. The method was simple, rapid and accurate.
