When HPLC fails: IC in food, water, and pharmaceutical analysis

High-performance liquid chromatography (HPLC) and ion chromatography (IC) are commonly used in the pharma, food, and environmental sectors to analyze samples for specific components and to verify compliance with norms and standards. However, users of HPLC may run into the limitations of this technique. This white paper outlines how such challenges can be overcome with IC. Using ion exchange as the separation mechanism, IC enables separation of many analytes that cannot be separated on HPLC columns. In this white paper, three example applications of IC are presented, one for each of the sectors including water, pharmaceuticals and food and beverages.
