The IonPac® ICE-AS6 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-AS6 column for organic acids in complex sample matrices.
- Use the ICE-AS1 column for the fast separation of organic acids.
- 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.
The weakly ionized acids are separated by pKa 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-AS6 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. The ICE-AS6 column provides improved peak efficiencies and selectivity for the carboxylic acids and alcohols. The ICE-AS6 column is ideally suited for most applications performed on the ICE-AS1 column. Use the Anion MicroMembraneTM Ion-Exclusion Suppressor (AMMS® ICE II) with the ICE-AS6 column.
