Thermo Scientific HAA9 Disinfection By-Products (HAAs) Application Workflow

The Thermo Scientific HAA9 Disinfection By-Products (HAAs) Application Workflow is designed to provide accurate and reproducible determination of haloacetic acids (HAAs) in drinking water samples.

Designed for use in municipal utility laboratories, contract testing laboratories and local or regional governing agencies performing water testing, the validated application workflow uses ion chromatography tandem mass spectrometry (IC-MS/MS) to achieve HAA analysis in drinking water in accordance with the US Environmental Protection Agency Method 557 (EPA 557).

The application workflow uses the Thermo Scientific Dionex ICS-6000 HPIC system and a Thermo Scientific Dionex IonPac AS31 column coupled with triple quadrupole mass spectrometry to deliver a fast, sensitive and simple method that has been developed for direct analysis of nine HAAs, bromate and dalapon in drinking water samples.

The MS detection method provides high sensitivity and makes it possible to directly inject drinking water samples, eliminating the complexity and variabilities of sample preparation. These method improvements allow time and cost savings for water testing laboratories and provide results that enable laboratories to more rapidly confirm the safety of drinking water.
