Dionex IonPac AS23-4µm Column Performance Test Using its QAR Method

Instrument Type: IC

Before running any samples, Thermo Scientific recommends that you first confirm the performance of the column by reproducing the lot validation report chromatogram shipped with column. Compare your results with the one reported in the quality assurance report. This record provides an eWorkflow for executing the QAR method on an Integrion HPIC system.

AN630: EPA Method 557 – Analysis of Haloacetic Acids, Dalapon, and Bromate in Drinking Water by IC-MS/MS: HAA9

Instrument Type: ICMS

Haloacetic acids (HAAs) are formed as disinfection byproducts when municipal chlorination processes react with naturally occurring brominated and chlorinated species. Five HAAs are currently regulated, whereas four others may be included in future regulations. Here we demonstrate the determinations of 0.02 to 0.1 ng/L (ppt) HAA9 concentrations using ion chromatography separations combined with tandem MS on a triple quadrupole mass spectrometry.

Determination of Trace Concentrations of Oxyhalides and Bromide in Municipal and Bottled Waters Using a Compact Ion Chromatography System

Instrument Type: IC

This record demonstrates that the method in AN167 can be run successfully using an Integrion Ion Chromatography (IC) system. AN 167 shows that IC with a hydroxide-selective Dionex IonPac AS19 column and electrolytic eluent generation is an efficient and sensitive approach for determining trace concentrations of disinfection biproduct (DBP) anions and bromide in municipal and bottled water samples. With this method the analyst can run US EPA Method 300.1 Part B.
