Disinfection byproducts from water treatment are suspected not only of being health hazards but even 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). Of primary concern is bromate, which forms from bromide during the ozonization of drinking water.

The microbore version of the Metrosep A Supp 7 - 250/4.0 is a high-performance separation column for the 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.

The high detection sensitivity is achieved through the use of the 5 µm polyvinyl alcohol polymer, with which extremely high plate numbers and thus outstanding separation and detection properties are achieved. In addition, the separation can be adapted to the specific requirements of the application by modifying the temperature.

This microbore column is particularly suitable for use with an MS detector.

Column dimensions (mm) : 250 x 2.0 Column type : 1 Maximum flow : 0.4 mL/min Housing material : PEEK Carrier material : Polyvinyl alcohol with quarternary ammonium groups Particle size (µm) : 5 pH range : 3...12 Max. pressure : 20 MPa Standard flow : 0.2 mL/min Temperature range (°C) : 20...60
