Microscopy is a key component in the research, formulation and manufacturing stages of pharmaceutical product development. Understanding and optimizing particle size, morphology and roughness of pharmaceutical materials is extremely important when developing a new drug compound and its delivery vehicle. Scanning electron microscopy (SEM) and optical microscopy are commonly used to assist in the optimization of these properties.
Understanding the size distribution and morphology of pharmaceutical particles containing either active pharmaceutical ingredients (API) or excipients is critical when optimizing dissolution rates of materials and compounding processes. Coupled with automated data acquisition and particle analysis software, SEM is ideal for determining the size and morphology of particles. Further, the chemical composition of particles in any given batch needs to be characterized when analyzing the efficacy of mixing or when checking for foreign particulate matter. SEM can also be paired with energy-dispersive X-ray spectroscopy (EDS) to analyze the chemical composition of individual particles with the Phenom ProX SEM.
Polarized light and interference contrast microscopies are used to investigate the crystal structure of components or elucidate solid or semi-solid particles suspended in a medium of similar contrast like a polymer or liquid. The Zeta-20 3D optical profiler is an extendable metrology platform that provides complete several different optical analyses including enhanced differential interference contrast (ZIC) in addition to the standard 3D profilometry.
