Thermo Scientific Dionex IonPac AS11-HC Hydroxide-Selective Anion-Exchange Column

For Resolving a Large Number of Inorganic Anions and Organic Acid Anions in Complex Matrices

Complex sample matrices such as chemical wastewater effluents and fermentation broth solutions contain a variety of inorganic anions and organic acids. The Thermo Scientific* Dionex* IonPac* AS11-HC column was specifically designed to resolve a large number of inorganic anions and organic acid anions in a single run using a hydroxide gradient. The new Dionex IonPac AS11-HC Capillary Column is packed with the same material as the equivalent standard bore and microbore versions (providing the same performance as a 4 mm and 2 mm column) but requires only 1/100th the eluent flow rate. The capillary format provides the advantage of significantly reduced eluent consumption, which helps reduce operating costs

Use for organic acids and anions in complex sample matrices or uncharacterized samples.
Recommended for monovalent and divalent organic acids.
Use the Dionex Ionpac AS11 for fast analysis of organic acids and anions in well-characterized samples.
Use the Dionex IonPac ICE-AS1 or ICE-AS6 columns for organic acids in high-ionic-strength samples.
High capacity translates into longer retention times, but with higher resolution.

The high-capacity Dionex IonPac AS11-HC column allows the injection of more concentrated samples without column overloading or peak broadening, and provides improved separation over the Dionex IonPac AS11 column for monovalent carboxylic acids, including quinate, lactate, acetate, propionate, formate, and butyrate.
