Controlled Release Testing Using Raman Chemical Imaging

    When developing controlled release products, it is important to establish coating consistencies in the laboratory and manufacturing environments to produce a predictable result.  The ability to effectively test and gain feedback about the coating processes for ingredient-specific measurements of individual coating layers, allows scientists to accurately predict the quality and performance of the product.  In addition, product attributes such as content conformity and particle size distribution effect dissolution properties.

    This webinar discusses specific methods of analysis for controlled release testing using Raman Chemical Imaging to measure layer thicknesses, content and blend uniformity of ingredients, particle size characterization, and polymorph analysis.  Specifically, we discuss how such analytical data is important in determining the quality and performance of a product.

    Highlighted Topics Covered:

    • Measuring layer thickness to understand and ensure product performance
    • Analysis of content and blend uniformity of ingredients and particle size characterization  to ensure proper dissolution properties
    • Analysis of polymorphs related to product performance and quality
