The method used a Thermo Scientific™ Dionex™ IonPac™ AS23-4μm column, a Thermo Scientific™ Dionex™ AERS™ 500 Carbonate anion electrolytically regenerated suppressor, and a Thermo Scientific™ Dionex™ CRD 300 Carbonate Removal Device in vacuum mode. This work demonstrates a similar method on a Thermo Scientific™ Dionex™ Inuvion™ ion chromatography system, a new integrated, single-channel compact IC system.
This study demonstrates the ability of the Thermo Scientific™ Dionex™ IonPac™ AS30 column to separate ethylenediamine (EDA) carbamate and fluoride as well as carbonate and sulfate in order to determine trace concentrations of oxyhalides and bromide in drinking water containing the EDA preservative.
This application note demonstrates the capability and performance of a Thermo Scientific™ Q Exactive™ HF hybrid quadrupole-Orbitrap mass spectrometer-based IC-HRAM MS method to identify and quantify nine haloacetic acids, bromate, and dalapon in drinking water.
Food safety and perceived health risks from residual agricultural chemicals are ongoing public concerns, and these chemicals are under increasing regulatory scrutiny, including polar pesticides. Much of the attention is focused on glyphosate because of its of wide use and association with crops and seeds genetically modified to tolerate glyphosate. In this application note, fast determination of multiple anionic pesticides and disinfection byproducts by IC-MS is demonstrated. All analytes of interest elute <14 min and were detected serially by suppressed conductivity and mass spectrometry.
This AN evaluated an IC-MS method for the determination of all nine haloacetic acids, bromate, and dalapon in drinking water using a Dionex ICS-6000 HPIC system couple with an ISQ EC single quadrupole mass spectrometer. Dionex IonPac AS31 column was used. It found that the IC-MS method is fast (40 min vs. 60 min in Method 557) and linear. It is sensitive (<1 μg/L), accurate and precise for the determination of U.S. EPA regulated HAA5, bromate, and dalapon. Critical IC system conditions important for successfully running this application are included.
