CONCENTRATION MAPPING OF COMPLEX MICROSTRUCTURES BY CONFOCAL RAMAN SPECTROSCOPY AND MULTIVARIANT ANALYSIS

Abstract: This paper shows how fully quantitative concentration images of complex microstructures can be obtained using confocal Raman spectroscopy. A number of measurement and data analysis obstacles needed to be examined and overcome. This included the spatial resolution limitation in the z-direction and spectrometer stability. An extension to the multivariant curve resolution (MCR) method is described that allows concentration maps to be produced. C r cha h prom y. How h exp by ana reso effe ins
