Note: The Dionex IonPac AS11 column is now recommended for fast analysis of organic acids and inorganic anions in well-characterized samples. Use the high-capacity Dionex IonPac AS11-HC column for organic acids and inorganic anions in complex sample matrices. Superior Chromatographic Performance
• Separates weakly ionized acids by differences in pKa, size, and hydrophobicity
• Elutes strong acid anions (e.g, chloride, oxalate and sulfate) in the void so they do not interfere with quantification of organic acids
• Ideal for electroactive ions such as cyanide and sulfite
• Achieves difficult separations, including formate, acetate, propionate and butyrate as well as cyanide, carbonate and borate
• Compatible with any typical strong acid eluent and a wide variety of detectors, including conductivity, amperometry, photometry and refractive index
• Uses HPLC solvents to control hydrophobic retention of higher-molecular-weight acids or for effective columncleanup Increased Sensitivity with Suppressed Conductivity Detection
• Dionex IonPac ICE-AS1 column should be used with the Dionex Anion MicroMembrane™ Ion-Exclusion Suppressor (AMMS™ ICE 300), which is a low-void volume, high-capacity eluent suppressor.
• The AMMS™ ICE 300 suppressor reduces the background conductivity of the eluent, while increasing the conductivity of the analytes.
