The composition of pharmaceutical tablets and the distribution of the ingredients therein can be determined using chemical imaging performed by vibrational microscopy. Doing so provides valuable information for manufacturing, troubleshooting, and counterfeit analysis.

Until recently, the applicability of vibrational microscopy was limited by the extensive analysis time required to obtain high-resolution chemical images. Now, with the maturity and commercialization of QCL-based IR laser imaging, complete tablets can be analyzed in a matter of minutes.

With this technology, high spatial resolution may be paired with state-of-the-art machine learning algorithms, providing a reliable, fast method to evaluate and visualize particle size and component distribution.
