• Polymer-based for broad pH stability
• Separates seven common inorganic anions

Because of their high pH stability, these columns are ideal for the separation of anions using high pH mobile phases such as p-hydroxybenzoate, sodium hydroxide, and sodium carbonate/bicarbonate. The larger dimension columns (150mm and 250mm) are suitable for a high resolution separation of the seven common inorganic anions.
