IonPac AS11 Hydroxide-Selective Anion-Exchange Column
For Fast Profiling of Inorganic Anions and Organic Acid Anions
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 samples
- Ideal for highly charged anions, including polyphosphates and polycarboxylates
- For organic acids and inorganic anions in complex sample matrices
- Low capacity translates into fast analysis times and high throughput
The 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.
