The AS11 is a relatively low-capacity column designed for fast, gradient screening of inorganic anions and organic acid anions in simple sample matrices.
Fast analysis of organic acids and inorganic anions in well-characterized samplesIdeal for highly charged anions, including polyphosphates and polycarboxylatesFor organic acids and inorganic anions in complex sample matricesLow capacity translates into fast analysis times and high throughputThe AS11 is designed for fast profiling of inorganic anions and organic acid anions in foods, beverages, chemical process solutions, wastewater, brines, and power plant waters. The AS11 column can resolve a large number of inorganic anions and organic acids in approximay 15 minutes.
