The IonPac Fast Anion IIIA is a hydroxide-selective, anion-exchange column designed for the rapid determination of phosphoric and citric acids in cola soft drink samples. 

The IonPac^® AS24 is a hydroxide-selective anion-exchange column designed for separation of haloacetic acids in drinking water prior to MS or MS/MS detection.  The capacity and selectivity allows for the analysis of haloacetic acids in drinking water at low µg/L concentrations.

The IonPac AS21 is a hydroxide-selective anion-exchange column designed for the fast analysis of trace perchlorate in drinking water prior to detection with MS/MS. The AS21 is the specified column in U.S. EPA Method 331.0.

The IonPac AS20 is a high-capacity, hydroxide-selective anion-exchange column designed for the determination of trace perchlorate in drinking water, groundwater, and other diverse sample matrices. The AS20 is the specified column for U.S. EPA Method 314.1 (Confirmatory Method).

The IonPac AS19 is the recommended hydroxide-selective, anion-exchange column for the determination of oxyhalides and inorganic anions, including fluoride, chlorite, bromate, chloride, nitrite, chlorate, bromide, nitrate, sulfate, and phosphate in a variety of sample matrices, including drinking water, groundwater, wastewater, and other diverse sample matrices. The key application for the AS19 is the determination of trace bromate in ozonated drinking water.

The IonPac AS18 is the recommended hydroxide-selective, anion-exchange column for the determination of inorganic anions, including fluoride, acetate, formate, chloride, nitrite, bromide, nitrate, sulfate, and phosphate, in a variety of sample matrices, including drinking water, wastewater, foods and beverages, industrial cooling waters, and scrubber solutions.

The IonPacAS17-C column is a hydroxide-selective anion exchange column designed for fast, gradient separation of common inorganic anions in a variety of sample matrices. The key application for the AS17-C column is the determination of common inorganic anions in high purity water matrices. The column provides low sulfate blanks and fast equilibration time for the analysis of trace anions in high purity water matrices. The AS17-C is the recommended replacement for all AS17 anion applications.

The IonPac AS17 is a low-capacity, hydroxide-selective, anion-exchange column designed for the determination of inorganic anions and low-molecular-weight organic acids, including fluoride, acetate, formate, chloride, nitrite, bromide, nitrate, sulfate, and phosphate, in simple sample matrices.

The IonPac AS16 is a high-capacity, hydroxide-selective column for hydrophobic anions (including iodide, thiocyanate, thiosulfate, and perchlorate) and polyvalent anions (including polyphosphates and polycarboxylates). The AS16 is the recommended column for trace perchlorate in drinking water and the specified column in U.S. EPA Methods 314.0 and 314.1 (Primary Method).

The IonPac AS15 column is a high-capacity, hydroxide-selective, anion-exchange column designed for the determination of trace-level concentrations of inorganic anions and low-molecular-weight organic acids in high-purity water matrices encountered in the semiconductor and power generation industries.

The IonPac AS11-HC is designed to resolve a large number of inorganic anions and organic acid anions in complex matrices, including foods, beverages, fermentation solutions, chemical additives, wastewater, brines, and power plant waters. The high-capacity AS11-HC column allows the injection of more concentrated samples without overloading or peak broadening.

The IonPac AS11 is a low-capacity, hydroxide-selective, anion-exchange column designed for the fast profiling of inorganic anions and organic acid anions in foods, beverages, chemical process solutions, wastewater, brines, and power plant waters.

The IonPac AS10 is a high-capacity, hydroxide-selective, anion-exchange column designed for the isocratic and gradient separation of inorganic anions and organic acids. The column provides excellent resolution of weakly retained low-molecular-weight aliphatic acids. The high capacity of the AS10 permits the analysis of anions and organic acids in nitrate samples.
