IonPac AS16 Anion-Exchange Column

The IonPac® AS16 column is designed specifically for trace perchlorate in drinking water in accordance with U.S. EPA Methods 314.0 and 314.1 (Primary Method). The Cryptand C1 Concentrator Column is the specified concentrator column for sample preconcentration in U.S. EPA Method 314.1. The IonPac AS20 can also be used for trace perchlorate analysis.  The AS20 is the specified column is U.S. EPA Method 314.1 (Confirmatory Method).  The AS16 column simplifies the determination of polarizable anions, including thiosulfate, iodide, thiocyanate, and perchlorate using an isocratic hydroxide eluent.

  • Isocratic separation of hydrophobic anions, including iodide, thiocyanate, and thiosulfate in less than 20 minutes.
  • Can be used for trace perchlorate in drinking water matrices. IonPac AS20 can also be used for trace perchlorate.
  • Ideal for polyvalent anions, including polyphosphates and polycarboxylates.
  • Simplified Reagent-FreeTM IC operation provided by the Eluent Generator, or the RFC-30 Controller, which requires only a deionized water source to produce potassium hydroxide eluent.
The IonPac AS16 column is a high-capacity, hydroxide-selective, anion-exchange column designed for the determination of polarizable anions in a variety of sample matrices. Under isocratic conditions, the polarizable anions can be determined in less than 20 min. Trace concentrations of perchlorate in drinking water, surface water, and groundwater matrices can easily be determined using a large-loop injection. With an isocratic hydroxide eluent, perchlorate can be determined in 10 min. The AS16 is recommended for use with RFIC systems using Eluent Generation, or the RFC-30 Controller. Use the Anion Self-Regenerating Suppressor (ASRS® ULTRA) with the AS16 column.

IonPac® AS20 Column

The new IonPac AS20 is the recommended hydroxide-selective column for trace perchlorate in drinking water.

Cryptand C1 Column

The IonPac® Cryptand C1 Concentrator column is the recommended concentrator column for the analysis of trace perchlorate in drinking water.

CR-TC Continuously Regenerated Trap Columns

Dionex's line of CR-TCs purify the eluent continuously.

SRS 300

The Self-Regenerating Suppressor, (SRS®  300), is used for electrolytically regenerated suppression of ion chromatography applications requiring high capacity, fast start-up, and sensitivity.

RFC-10 and RFC-30

Want to stop manually preparing eluent and regenerants?

Reagent-FreeTM IC with Eluent Generation (RFIC-EGTM ) systems reduce errors and provide consistency in your results, all by just adding water. The RFC-30 allows users to upgrade existing systems to RFIC-EG systems at a reasonable price.
