FAQs

Question: Is this IonPac AS11 an analytical or guard column?

Answer:This version is the 4 × 250 mm analytical column.

Question: What types of analytes is the AS11 designed to separate?

Answer:It is designed for inorganic anions and organic acid anions using ion chromatography.

Question: What guard column matches the 4 mm AS11 analytical format?

Answer:The matching guard format is the 4 × 50 mm AG11 column.

Application Note

Dionex™ IonPac™ AS11 Analytical Column is used for gradient ion chromatography of inorganic anions and organic acid anions. This configuration is the 4 × 250 mm analytical column, not the shorter guard column. The AS11 is a relatively low-capacity anion-exchange column designed for rapid gradient screening in comparatively simple sample matrices such as foods, beverages, chemical-process solutions, wastewater, brines and power-plant waters. Hydroxide eluents can separate weakly retained monovalent anions together with more strongly retained multivalent species in the same gradient program. The column can also be used with hydroxide/methanol conditions for strongly retained anions. Its 4 mm standard-bore format is suited to conventional ion-chromatography systems and pairs with the matching 4 × 50 mm AG11 guard column when additional protection is required.
