Title:
MASS SPECTROMETRY METHOD FOR PERFLUOROALKYL ETHER CARBOXYLIC ACID AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/088166
Kind Code:
A1
Abstract:
The present invention relates to a mass spectrometry method for perfluoroalkyl ether carboxylic acid (PFECA) and the use thereof. In the present invention, [CF3(CF2)nO] or [M-H-CO2] is selected as a parent ion, other fluorinated alkoxy and alkyl fragments are used as daughter ions, new ion pairs are constructed, and ultra-sensitive detection of PFECA in various samples is achieved by optimizing cone voltage and collision energy.
