Complex sample matrices such as chemical wastewater effluents and fermentation broth solutions contain a variety of inorganic anions and organic acids. The IonPac® AS11-HC was specifically designed to resolve a large number of inorganic anions and organic acid anions in a single run using a hydroxide gradient.
The high-capacity AS11-HC column allows the injection of more concentrated samples without column overloading or peak broadening, and provides improved separation over the AS11 column for monovalent carboxylic acids, including quinate, lactate, acetate, propionate, formate, and butyrate.
