The IonPac^® ICE-AS1 ion-exclusion column is designed for the fast analysis of aliphatic organic acids and alcohols in complex, or high-ionic-strength samples, including foods and beverages, biological samples, fermentation processes, industrial process liquors, and wastewaters.

• Use the ICE-AS1 column for the fast separation of organic acids.
• The ICE-AS1 is ideal for electroactive ions such as cyanide and sulfite.
• Use the ICE-AS6 column for organic acids and alcohols in complex sample matrices.
• Use the low-capacity AS11 column for the fast analysis of organic acids and inorganic anions in well-characterized samples.
• Use the high-capacity AS11-HC column for organic acids and inorganic anions in complex sample matrices or uncharacterized samples.

With the IonPac ICE-AS1 column, the weakly ionized acids are separated by pK_a differences, size, and hydrophobicity. Strong acid anions such as chloride, oxalate, and sulfate elute in the void and do not interfere with the quantification of the organic acids. The ICE-AS1 column can be used with any typical strong acid eluent and a wide range of detectors, including conductivity, amperometry, photometry, and refractive index to determine aliphatic organic acids. Use the Anion MicroMembrane^TM Ion Exclusion Suppressor (AMMS^® ICE II) with the ICE-AS1 column.
