Abstract

Two- and three-dimensional spatial analysis of various composite materials was performed with a scanning confocal Raman microspectrometer. Samples include TiO2 microparticles, mixtures of polymers, and the surface of an older Eprom computer chip. In the last case both structural and compositional information was obtained by means of comparing the signal intensity of the Rayleigh line with that of the silicon Raman line at 520 cm-1. The spatial compositions of a pain-relief medicine and a pharmaceutical salt mixture could be visualized from characteristic Raman lines of the components.
