Analysis of impurities in pharmaceuticals using ion chromatography

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.

Metrohm can help you with validating a method, modernizing or converting methods (titration or HPLC to IC), implementing column equivalency, and searching for USP-compliant Metrohm applications.

Bring your USP methods up to date

This webinar presents ion chromatography as a sensitive and selective technique for monitoring ionic and polar impurities. A variety of detectors and columns are available to best suit your application.

Metrohm IC systems can be automated and extended with Metrohm Inline Sample Preparation techniques, such as Inline Ultrafiltration, Inline Dilution, or Inline Matrix Elimination, as well as injection techniques, such as Partial Loop Injection. As discussed in the webinar, automation and inline sample preparation improve the efficiency of your IC system, reduce human errors, and ensure a longer lifetime of the column, leading to lower costs.

Metrohm ion chromatography instruments are:

• Robust: We grant a 3-year warranty on our Swiss-made instruments and a 10-year warranty on the anion suppressor.
• Compliant: GLP compliance and data integrity, security, and traceability as per FDA 21 CFR Part 11, ALCOA, and ALCOA+.
• Easy to maintain and service: We are present in 40 countries with subsidiaries and in more than other 40 countries with exclusive partners.
