IonPac AS21

by Dionex

 

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.

Similar columns from other manufacturers to IonPac AS21

Up to 10 unique Brand families from other Vendors with the same Mode and the same Modification.

How similarity is calculated
Eligible families receive a weighted score from Modification (25%), Product Usage (20%), Carbon Load (15%), Endcapping (10%), Pore Size (10%), Surface Area (8%), pH Stability (8%) and Particle Size (4%). The score uses data available in both families and requires at least three comparable criteria, at least 50% data coverage and a minimum 55% score. A relevant active sponsor may appear first and is always labelled Sponsored.
A similarity score does not guarantee identical selectivity or performance. Confirm suitability under the intended method conditions.
