Anion separation column for use with chemical suppression. For determination of oxyhalides.

Disinfection byproducts from water treatment are suspected not only of being health hazards but also of being carcinogenic. Oxyhalides have therefore become the subject of many investigations and standards (e.g., EPA 300.1 Part B, EPA 317.0, EPA 326.0). Bromate is the primary concern, which forms from bromide during the ozonization of drinking water.

The Metrosep A Supp 7 - 250/4.0 is a high-performance separation column for parallel determination of standard anions, oxyhalides and dichloroacetic acid. With this column, these ions are determined with certainty and precision down to the lower µg/L range. High detection sensitivity is achieved by using the 5 µm polyvinyl alcohol polymer, which allows extremely high plate numbers and therefore outstanding separation and detection properties to be achieved. In addition, the separation can be adapted to the specific requirements of the application by modifying the temperature.
