Note: The high-capacity Dionex IonPac AS11-HC column is now recommended for determination of organic acids and inorganic anions in complex sample matrices or uncharacterized samples. Superior Chromatographic Performance The Dionex IonPac ICE-AS6 provides improved peak efficiencies and selectivity for carboxylic acids and alcohols. Specifically, it:
• Separates weakly ionized acids by differences in pKa, size, and hydrophobicity
• Elutes strong acid anions (e.g, chloride and sulfate) into the void so they do not interfere with quantification of organic acids
• Achieves difficult separations, including tartrate from citrate, glycolate from lactate and formate, lactate from malate, and formate from succinate
• Is compatible with any typical strong acid eluent and a wide variety of detectors, including amperometry, photometry, and refractive index
• Uses HPLC solvents to control hydrophobic retention of higher- molecular-weight acids or for effective column cleanup 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.
