Strategy for streamlined release identity testing of chromatography media

Area of Science:

• Pharmaceutical Science
• Analytical Chemistry
• Quality Control

Background:

• Chromatography media identity testing is crucial for human pharmaceutical production per 21 CFR 211.84.
• Complex media properties like variable morphology and insolubility pose challenges for traditional identification methods.
• Existing methods may not adequately address the unique characteristics of diverse chromatography media.

Purpose of the Study:

• To develop a robust and routine strategy for identifying chromatography media.
• To address the challenges posed by complex physical and chemical properties of these materials.
• To ensure compliance with regulatory requirements for pharmaceutical manufacturing.

Main Methods:

• Utilized Fourier transform infrared (FT-IR) and near-infrared (NIR) spectroscopy with library searching.
• Incorporated particle size distribution analysis as a complementary identification technique.
• Developed a hierarchical selection procedure for a systematic identification process.

Main Results:

• The combined spectroscopic and particle size analysis approach provides specific media identification.
• The methods are suitable for routine application in a quality control laboratory setting.
• A hierarchical strategy allows for unique identity assignment for each chromatography medium.

Conclusions:

• The proposed strategy offers a reliable method for chromatography media release testing.
• The generic nature of the technology allows for broad applicability to various chromatography media.
• This approach enhances quality control in pharmaceutical manufacturing by ensuring media identity.
