The new IonPac^®  AS23 is a very high-capacity anion-exchange column and is the recommended carbonate-based column designed for inorganic anions and oxyhalides.  The AS23 is recommended for trace bromate in drinking water. This column meets performance requirements specified in U.S. EPA Methods 300.1 and 317.0.

The IonPac  AS22 is a very high-capacity anion-exchange column and is the recommended carbonate-based column for the fast, isocratic separation of inorganic anions, including flouride, chloride, nitrite, bromide, nitrate, phosphate, and sulfate, using a carbonate/bicarbonate eluent.

The IonPac AS14A is a high-capacity, carbonate-based, anion-exchange column designed for the fast, isocratic separation of inorganic anions, including fluoride, chloride, nitrite, bromide, nitrate, phosphate, and sulfate, using a carbonate/bicarbonate eluent.

The IonPac AS14 is a moderate-capacity, carbonate-based, anion-exchange column designed for the fast, isocratic separation of inorganic anions, including fluoride, chloride, nitrite, bromide, nitrate, phosphate, and sulfate using a carbonate/bicarbonate eluent.

The IonPac^® AS12A is a moderate-capacity, carbonate-based, 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 environmental water matrices.

The IonPac  AS9-HC is a carbonate-based, high-capacity column designed for inorganic anions and oxyhalides. The AS9-HC can be used for trace bromate in drinking water. This column is specified in U.S. EPA Methods 300.1 and 317.0.

The IonPac AS9-SC is a carbonate-based, low-capacity column designed for the fast analysis of inorganic anions and oxyhalides. This column is specified in U.S. EPA Method 300.0 (B).

The IonPac AS4A-SC (solvent-compatible) is a low-capacity, carbonate-based, anion-exchange column designed for the fast, isocratic separation of inorganic anions in diverse sample matrices.
