DESCRIPTION
Obtain consistent, reliable results for the determination of disparate concentration ratios of ethanolamine and ammonium in diverse sample matrices using the Thermo Scientific™ Dionex™ IonPac™ CS15 Cation-Exchange Column. This is a medium-capacity carboxylate-functionalized cation-exchange column with crown ether moiety. The column has unique selectivity, and is the only carboxylic acid based cation column from Dionex in which ethanolamines elute before ammonium. Thus, it is the column of choice for samples with high ammonium to low ethanolamine ratios.
