AS11-HC column used to resolve a larger number of inorganic anions and organic acid anions in complex matrices.

• Higher concentration samples injected without column overloading or peak broadening
• Requires longer retention times, but with higher resolution
• Facilitates rapid analysis in well-characterized samples
• Ideal for complex sample matrices or uncharacterized, for monovalent and divalent organic acids

Designed to resolve analytes in a single run using a hydroxide gradient. The high-capacity column delivers improved separation for monovalent carboxylic acids including quinate, lactate, acetate, propionate, formate, and butyrate.

Complex matrices such as chemical wastewater effluents and fermentation broth solutions contain a variety of inorganic anions and organic acids.
