This white paper discusses using Raman Chemical Imaging as method to analyze dry powder formulations containing multiple active ingredients in order to obtain important data about the aerosolization behavior that was previously unavailable. This analysis offers developers new opportunities to optimize the formulations and the delivery devices for combination therapies.

This white paper discusses using Raman Chemical Imaging as method for spatially resolved, chemically-specific analysis of particles that contain multiple active ingredients in order to verify the composition of the particles, which is critical for process optimization, and regulatory requirements. Reviews method used for determining the ratio of drug components.

This white paper reviews the importance of measuring particle size distribution and degree of aggregates in nasal spray formulations. Raman chemical imaging is presented as a greatly improved method of analyzing aggregates and agglomerates in nasal spray suspension formulations. Reviews the time and cost savings compared to current practice.
