USP-standardized analyses with ion chromatography: Simple, efficient, and robust

The United States Pharmacopeia (USP) has updated and modernized existing monographs across all compendia to include ion chromatography (IC) methods for pharmaceutical assays and for the analysis of impurities and excipients. IC is a robust multi-parameter analysis technique that is flexible, easy to use, and suited for the determination of anions, cations, and any other kind of charged molecules.

Metrohm has partnered with the USP for ion chromatography method development and offers you robust solutions for your standardized pharmaceutical analyses. A detailed list of USP monographs that were developed and validated with Metrohm IC instruments can be found in this flyer:

Ion chromatography and USP – Your benefits

Ion chromatography is a well established and accepted regulatory method for analyzing anions and cations in pharmaceutical drug substances and drug products.

Compared to single-parameter methods, such as titration, ion measurements, and other wet chemical procedures, ion chromatography is:

  • More efficient: Multiple parameters are determined in one go
  • More selective: Target analytes are clearly identified
  • Safer: Hazardous procedures and materials such as solvents, reagents, and other chemicals are not required

Why Metrohm Ion Chromatography? – We make the difference
