When HPLC fails: IC in food, water, and pharmaceutical analysis
2 Dec 2019High-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.

UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems.
