Characterization of alkylphosphonic acid vapors using atmospheric flow tube–ion trap mass spectrometry

Abstract

A key aspect of detecting hazardous compounds at ultra‐trace levels for processing, compliance, and clean‐up purposes involves developing methods that are not only sensitive, but also highly selective with minimal sampling effort. Atmospheric flow tube mass spectrometry (AFT‐MS) using dielectric barrier discharge ionization has emerged as a technique that combines such features for vapor detection. AFT‐MS is thus appealing for application to ambient screening for chemical warfare agents (CWAs) and their degradation products. Initial characterization of AFT‐MS for CWA detection necessitates examining less harmful simulant species. A predominant hydrolysis product of most organophosphorus CWAs is methylphosphonic acid and most other hydrolysis products consist of some form of an alkylphosphonic acid.
