TN001521: Choosing the Appropriate Cation-Exchange Column for Quaternary Amine Determinations
Description
The goal of this work is to evaluate and identify cation-exchange columns suitable for applications involving quaternary amine compound (QAC) determinations. Four Thermo Scientific Dionex IonPac columns (CS17, CS19-4µm, CS20, and CS21-4µm) were evaluated. A Thermo Scientific™ Dionex™ ICS-5000+ HPIC™ system that produced an electrolytically generated methane sulfonic acid (MSA) eluent was used for this work. The results for retention time, peak area, peak asymmetry, and efficiency are included here along with recommendations for choosing a column for QAC determinations.| Market: | Environmental |
