IonPac AS21 Hydroxide-Selective Anion-Exchange Column

For Fast Analysis of Trace Perchlorate in Drinking Water Prior to Detection with MS/MS

The AS21 hydroxide-selective anion-exchange column is specifically designed for determination of trace perchlorate in drinking water prior to MS/MS detection. The capacity and selectivity enable fast analysis of perchlorate at low μg/L concentrations. The AS21 is the specified column in US EPA Method 331.0.

Fast separation of perchlorate prior to MS/MS detection
Optimized for methylamine or hydroxide mobile phases
Specified column for US EPA Method 331.0
Optimum capacity: 45 μeq per column (2 × 250 mm)
Operates at ambient or elevated temperatures
Compatible with organic solvents

The AS21 2 × 250 mm column format was specifically developed for MS/MS compatibility to allow use of volatile mobile phases such as methylamine.
