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.
