Isolating Particles of Interest Within Formulations Using Chemical ID With Image Analysis

During the manufacture of blends the most important ingredient (API, active pharmaceutical ingredient) needs to be monitored to ensure it maintains it potency and homogeneity. Differences seen in particle size and shape may result in potential performance issues. Manual microscopy and visual identification of the active particles within a blend can be time consuming, subjective and inaccurate, all of which can lead to increased manufacturing costs by wasting valuable company time and resources.

The release of the Morphologi G3-ID from Malvern Instruments provides a unique capability, combining automated static imaging with chemical identification of individual particles using Raman spectroscopy in one platform. Integrated dry powder dispersion automates sample preparation for repeatable and reproducible measurements of both fragile and robust materials. The software enables simple operation with automatic selection, targeting and chemical classification of 1000’s of individual particles.

Malvern’s recent application note describes how the combination of automated image analysis with Raman spectroscopy in the Morphologi G3-ID can be applied to increase both the accuracy and robustness of these types of measurements by chemically identifying and isolating the particles of interest within a topical cream formulation. Differentiation of morphologically similar APIs was achieved through Raman analysis.
