This anion-exchange column attain the optimal combination of chromatographic speed and resolution, provides excellent resolution of inorganic anions in diverse sample matrices.

• Constructed of PEEK with 10 to 32 threaded ferrule-style end fittings
• All components are nonmetallic
• Super macroporous resin composition
• Mobile phase compatibility of pH 0 to 14; 0 to 100% HPLC solvents

This is the hydroxide-selective column of choice for fastest compliance monitoring of inorganic anions in drinking water and wastewater samples in accordance with U.S

The Dionex IonPac AS18–4 µm anion-exchange column uses smaller resin particles for more efficient peaks resulting in faster run times, more accurate peak integration, and more reliable results.

EPA Methods 300.0 (A) and 300.1.
