Full Description

A new method that combines electrospray ionization mass spectrometry with non-chromatographic analyte separation has been shown to be a highly sensitive and rapid method for the analysis of haloacetic acids in drinking water. The technique, known as electrospray ionization - high field asymmetric waveform ion mobility spectrometry-mass spectrometry (ESI-FAIMS-MS), allows detection limits rivaling those of GC-based methods, but with the advantage of no sample work-up, derivatization or chromatographic separation required. Good comparison with EPA Method 552.2 for dichloroacetic acid (DCAA) and trichloroacetic acid (TCAA) in different municipal drinking waters is observed. Includes 7 references, table, figures.
