IonPac AS12A Carbonate Eluent Anion-Exchange Column

Fast Separation of Inorganic Anions, with Excellent Retention of Fluoride

The IonPac^? AS12A anion-exchange column provides fast analysis of common inorganic anions and oxyhalides, such as chlorite and bromate, in environmental waters. This column is also useful for trace chloride and sulfate in high-carbonate matrices.

• Provides fast analysis of inorganic anions and oxyhalides at similar concentrations
• Resolves trace chloride and sulfate high-carbonate samples

The AS12A is a moderate-capacity, carbonate eluent anion-exchange column designed for the fast, isocratic separation of inorganic anions and oxyhalides, including fluoride, chlorite, bromate, chloride, nitrite, bromide, chlorate, nitrate, phosphate, and sulfate in drinking water, wastewater, groundwater, and other diverse sample matrices.

The common inorganic anions and oxyhalides can be determined in less than 12 min using an isocratic carbonate/bicarbonate eluent coupled with suppressed conductivity detection. It resolves chloride from high concentrations of carbonate. Use the Anion Self-Regenerating Suppressor (ASRS^? 300) with the AS12A column.

Note: For trace bromate in ozonated drinking water, use the high-capacity IonPac AS23, recommended for determination of oxyhalides and inorganic anions.
