Fast Validated Direct Injection Determination of HAAs in Drinking Water with IC-MS/MS by EPA 557

Speaker

Abstract

Haloacetic acids (HAAs) are among the disinfection byproducts produced during chlorination of water. EPA method 552.3 using GC-ECD requires extraction and derivatization that can take up to 4 hours. Ion chromatography-mass spectrometry (IC-MS/MS), per EPA Method 557 provides results that can be analyzed in 35 min. This presentation shows (IC-MS/MS) system to system variability with results from a repeatability study of multiple systems using HAA9, Bromate, and Dalapon.
