Raman spectroscopy has been used to analyze the process of micro-encapsulation of flavors. This contribution shows the example of distribution of limonene and quantification of its content within the micro-particles.

Exposure to warm/humid conditions may cause pharmaceutical formulations to undergo change in hydration level, affecting properties and/or efficiency of the drug. Raman spectroscopy, with a temperature and humidity controller can mimic harsh conditions, monitor properties of ingredients and track modifications induced by environmental changes.

The use of the transmission Raman mode instead of the traditional backscattering one brings additional flexibility for the analysis of material, especially when averaged information of bulky samples is required.

Full and detailed characterization of pharmaceutical formulations is required before the release of new drugs.
