Dionex IonPac AS16 Hydroxide-Selective Anion-Exchange Column

High-Capacity Column Optimized for Determination of Polarizable Anions

The Thermo Scientific? Dionex? IonPac? AS16 column is ideally suited for trace perchlorate in drinking water in accordance with US EPA Methods 314.0 and 314.1 (Primary Method). The Dionex IonPac AS16 column simplifies the determination of polarizable anions, including thiosulfate, iodide, thiocyanate, and perchlorate using an isocratic hydroxide eluent.

Separate hydrophobic anions (iodide, thiocyanate, and thiosulfate) in less than 20 min
Can be used for trace perchlorate in drinking water matrices
Ideal for polyvalent anions, including polyphosphates and polycarboxylates
Ultralow hydrophobicity allows fast analysis of polarizable anions

The Dionex IonPac AS16 is a high-capacity, hydroxide-selective column for the determination of polarizable anions in a variety of sample matrices. Trace concentrations of perchlorate in drinking water, surface water, and ground water matrices can easily be determined using a large-loop injection. The Dionex IonPac AS16 column is available in three formats: standard bore (4 × 250 mm), microbore (2 × 250 mm) and capillary (0.4 × 250 mm). The capillary format is packed with the same material as the equivalent standard bore and microbore versions (providing the same performance as a 4 mm and 2 mm column) but requires only 1/100th the eluent flow rate. The capillary format provides the advantage of significantly reduced eluent consumption, which helps reduce operating costs. The Dionex IonPac AS16 capillary column is used in the second dimension of the 2D-IC method for the analysis of trace perchlorate (sub ppb) in drinking water.

Note: Also see the Dionex IonPac AS20, with complementary selectivity for confirmation of perchlorate identification when using EPA Method 314.1
