Apr 16 2021 Read 59 Times Municipal utility laboratories, contract testing laboratories, and local or regional governing agencies performing water testing can now benefit from a new, validated application workflow using ion chromatography tandem mass spectrometry (IC-MS/MS) to achieve haloacetic acid (HAA) analysis in drinking water in accordance with the U.S. Environmental Protection Agency Method 557 (EPA 557). The new Thermo Scientific™ Disinfection By-Products (HAAs) 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.
