摘　　要：邻苯二甲酸二异壬酯是一种高关注的增塑剂,由于本身特性,其色谱图是五指峰,这给定量工作增加了复杂性。文章研究引入一种相对安全的增塑剂——对苯二甲酸二辛酯,借助两种物质在出峰时间上有重叠且具有相同特征离子的条件,利用仪器自带的分析软件建立更为便捷的定量方法,新方法的线性达到0.999,精密度高于传统方法,达到了获得更高的工作效率与更理想的效果双重目标。Diisonyl phthalate is a kind of plasticizer of high concern. Because of its own characteristics, its chromatogram is five finger peak, which increases the complexity of quantitative work. In this paper, a relatively safe plasticizer, dioctyl terephthalate, is introduced. Under the condition that the two substances overlap in the peak time and have the same characteristic ions, a more convenient quantitative method is established by using the analysis software provided by the instrument. The linearity of the new method is 0.999, and the precision is higher than that of the traditional method, thus achieving higher working efficiency and better results.
