Have Questions?
When you need to quickly separate perchlorate in drinking water prior to detection with MS/MS, the Thermo Scientific™ Dionex IonPac AS21 hydroxide-selective anion-exchange column is column of choice. This column is specifically listed in U.S. EPA Method 331.0. The column's capacity and selectivity enable fast analysis of perchlorate at low μg/L concentrations. In addition, the 2x250 mm column format was designed and optimized for LC-MS or LC-MS/MS compatibility to facilitate use of volatile mobile phases such as methylamine.
