Analysis of Nerve Agent Degradation Products Using Capillary Ion Electrophoresis

摘要

A method has been developed for the analysis of nerve agent degradation productsusing capillary ion electrophoresis. Analysis of the primary degradation products isopropyl methylphosphonic acid (IMPA), ethyl methylphosphonic acid (EMPA), pinacolyl methylphosphonic acid (PMPA), and methylphosphonic acid (MPA) was accomplished with run times of <5 min. Detection of low milligrams/liter levels of degradation products in spiked water samples was possible. The analysis of the alkyl methylphosphonic acids required little sample preparation.
