AN72209: Determination of Trace Concentrations of Oxyhalides and Bromide in Municipal and Bottled WatersInstrument Type: IC
To demonstrate that oxyhalides and bromide can be successfully determined at concentrations required for regulatory standards and guidelines using a Thermo Scientific™ Dionex™ ion chromatography system equipped with a Thermo Scientific™ Dionex™ IonPac™ AS23-4μm column,Thermo Scientific™ Dionex™ CRD 300 Carbonate Removal Device, and a Thermo Scientific™ Dionex™ AERS™ 500 Carbonate Anion Electrolytically Regenerated Suppressor.
AU203: Determination of Trace Concentrations of Oxyhalides and Bromide in Municipal and Bottled Waters Using a Compact Ion Chromatography SystemInstrument Type: IC
To demonstrate that oxyhalides and bromide can be run successfully using a Thermo Scientific™ Dionex™ Integrion™ HPIC™ system combined with a Thermo Scientific™ Dionex™ IonPac™ AS19-4μm column, featuring smaller resin particles, to achieve faster analysis without compromising data quality compared to using the Dionex IonPac AS19 column as in Application Note 167.
EPA Method 557 - Analysis of Haloacetic Acids, Dalapon, and Bromate in Drinking Water by IC-MS/MSInstrument Type: ICMS
Haloacetic acids (HAAs) are formed as disinfection byproducts when water is chlorinated to kill bacteria. Chlorine reacts with naturally occurring organic and inorganic matter in the water, such as decaying vegetation, to produce disinfection by-products (DBPs) that include HAAs. Of the nine species of HAAs, five are currently regulated by the U.S. Environmental Protection Agency (EPA). We demonstrate a simple and sensitive IC-MS/MS method for analyzing haloacetic acids, the pesticide dalapon, and bromate in water using EPA Method 557.
Determination of Trace Concentrations of Oxyhalides and Bromide in Municipal and Bottled Waters Using a Compact Ion Chromatography SystemInstrument 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.
AU154: Determination of Bromate in Drinking and Mineral Water by Isocratic Ion Chromatography with a Hydroxide EluentInstrument Type: IC
Ozone is a powerful drinking water disinfectant that is effective in treating chlorine resistant organisms. Ozonation is an effective disinfection process that is used worldwide, but will produce bromate if the source water contains bromide. Bromate is a potential human carcinogen and its concentration in drinking water is regulated in many countries. This application update shows that bromate, chlorate, and chlorite can be determined with an isocratic hydroxide eluent to easily meet current bromate regulations.
