Adapting HPLC to the Capillary Scale: Insights from Academia and Industry

Learn how scientists are adapting analytical high-performance liquid chromatography (HPLC) methods to the capillary scale—cutting solvent use, improving sensitivity, and adapting validated pharmaceutical monographs to the capillary scale without the need for revalidation.

Adapting high-performance liquid chromatography (HPLC) methods to the capillary scale opens new possibilities for pharmaceutical analysis and sustainability. This joint session with the University of Pavia and Axcend examines real-world method conversions that preserve performance while minimizing waste. Case studies include detection of a polar impurity in pediatric ibuprofen mini-tablets using a micro-HPLC-UV method, and a USP <621>-guided adaptation for hydrochlorothiazide demonstrating over 99% solvent reduction. Attendees will gain insight into practical guidelines, expected trade-offs, and data from both academic and regulated environments, offering a roadmap to adapting validated pharmaceutical monographs to the capillary scale without the need for revalidation.

Key Learning Objectives:

• Adapt pharmaceutical monographs to the capillary scale without revalidation
• Identify expected performance gains and trade-offs at low-flow rates
• Explore real-world data from academic and regulated environments
