Precise, Isocratic Analysis of Trace Oxyhalides and the Common Inorganic Anions
The
Thermo Scientific? Dionex? IonPac? AS23 carbonate eluent anion-exchange
column is specifically designed for trace bromate in drinking water.
Its high-capacity and selectivity enables determination of bromate in
drinking water at the low μg/L level. The Dionex IonPac AS23 column
meets the performance requirements of U.S EPA Methods 300.0 and 300.1.
The Dionex IonPac AS23 column is offered in three formats: standard bore
(4 × 250 mm), microbore (2 × 250 mm) and capillary (0.4 × 250 mm). The
capillary formats is packed with the same material as the equivalent
standard bore version (providing the same performance as a 4 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.
-
Optimized for isocratic carbonate/bicarbonate eluent
-
Recommended column for trace bromate in drinking water matrices
-
Meets performance requirements specified in U.S. EPA Methods 300.0 and 300.1
-
Ideal alternative for the Thermo Scientific Dionex IonPac AS9-HC oxyhalide and inorganic anion applications
-
Simple, accurate eluent preparation with the Dionex IonPac AS23 Eluent Concentrate
-
Optimized for a 30 °C operating temperature to ensure reproducible retention times
-
Compatible with organic solvents to enhance analyte solubility
The
Dionex IonPac AS23 column is designed for the analysis of oxyhalides
and the common inorganic anions including fluoride, chlorite, bromate,
chloride, nitrite, bromide, chlorate, nitrate, phosphate, and sulfate in
drinking water, ground water, wastewater, and other diverse sample
matrices.
The Dionex IonPac AS23 column is the newest carbonate
eluent column recommended for the analysis of oxyhalides including
bromate. It can be used in combination with the Eluent Generator and the
Electrolytic pH Modifier (EPM) which automatically produces potassium
carbonate/bicarbonate eluents from water. The Dionex IonPac AS23 column
is an ideal alternative, using carbonate-bicarbonate eluents, for Dionex
IonPac AS9-HC applications.
