AI Article Synopsis
- - Perfluoroalkyl carboxylic acids (-PFCAs) are becoming recognized as new environmental pollutants that pose detection challenges.
- - The small collision cross sections (CCS) of -PFCAs hinder their identification through ion mobility techniques.
- - Research suggests that internal hydrogen bridging in -PFCA ions is responsible for their small CCS, providing a pathway for developing improved identification methods for these pollutants.
Article Abstract
-Perfluoroalkyl carboxylic acids (-PFCAs) are emerging pollutants. Their identification by ion mobility is frustrated by the -PFCAs having unexpectedly small collision cross sections (CCS). Theory and experiment agree that this is because -PFCA ions undergo internal hydrogen bridging, and this insight will help guide the creation of more accurate methods for pollutant identification.
