Ion-Exclusion Column for Aliphatic Organic Acids and Alcohols in Complex Samples. The IonPac® ICE-AS6 ion-exclusion column is designed for fast analysis of aliphatic organic acids (including hydroxyl-substituted organic acids) and alcohols in complex or high-ionic-strength samples, including foods and beverages, biological samples, fermentation baths, industrial process liquors, and wastewaters. The ICE-AS6 column is ideally suited for most applications performed on the ICE-AS1 column.The ICE-AS6 column provides improved peak efficiencies and selectivity for carboxylic acids and alcohols. 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 quantificat...Read more
