Transmission Raman Offers Improved Quantitation of Pharmaceutical Solids

June 01, 2009

Manufacturing control of pharmaceutical solids requires routine measurement of content uniformity. Because of the high information content in Raman spectra, it has been considered a candidate technology for making these measurements.

Raman and EDXRF Chemical Imaging for Formulation Process Development and Quality Control

June 02, 2005

Compounds of magnesium and calcium are common components of pharmaceutical formulations. Spectroscopic imaging can provide a complete understanding of a formulation. This paper compares two spectral imaging techniques — energy dispersive X-ray fluorescence (EDXRF) microscopy and Raman microscopy.
