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
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.
