This webinar will describe particle characterization, including particle size determination and Raman spectroscopic evaluation, from a pharmaceutical perspective. The first part of the webinar will discuss particle size analysis, including laser diffraction and image analysis by Jeff Bodycomb of HORIBA. Next, pharmaceutical applications will be discussed by Rob Lee of Particle Sciences. Case studies will include particle size determination of an active pharmaceutical ingredient in semi-solid gels, spectroscopic characterization of drug-eluting devices (i.e., intravaginal rings), and comments on method development and validation of particle size distribution measurements.
