The United States Pharmacopeia (USP) is constantly trying to modernise pharmaceutical testing methods. In their efforts, ion chromatography (IC) has become increasingly recognised as a powerful alternative for potassium analysis. Metrohm’s applications demonstrate just how IC can accurately determine potassium levels while also identifying impurities, such as sodium and ammonium, in pharmaceutical products and dietary supplements.
Unlike traditional techniques, IC eliminates the need for flammable gases whilst also increasing efficiency through multi-ion analysis in a single run. Additionally, high-capacity separation columns reduce the need for manual sample preparation, even with complex sample matrices.
Metrohm’s validated IC methods align with USP requirements, providing pharmaceutical manufacturers with reliable, compliant and streamlined workflows. By aiding the transition towards modern analytical techniques, Metrohm continues to help labs improve accuracy, efficiency and confidence in pharmaceutical quality control.
