用大气压电喷雾质谱快速鉴定表面活性剂

Rapid Identification of Surfactants by ESI/MS

本文介绍了用大气压电喷雾质谱快速鉴定日化产品中表面活性剂的方法。表面活性剂在水溶液中离解成离子或结合水溶液中Na而带正电 ,可用大气压电喷雾质谱对其结构及组成进行鉴定 ,利用该方法亦可于 5分钟内鉴定两种或多种混合表面活性剂。

Rapid identification of surfactants in household products by ESI/MS was discussed in this paper.The structure and composition could be charactered by ESi/MS due to their dissociation as ions or being charged in solution.In addition,two or more mixed surfactants were identified within 5 minutes.
