APPLYING RAMAN SPECTROCOSPY AND MULTIVARIATE STATISTICAL ANALYSIS TO THE CHARACTERIZATION OF MINERALS

摘要

In this presentation we have described several examples of using Raman spectroscopy to analyze various minerals. The combination of a research grade Raman spectrometer and a high quality data base of reference spectra provides a powerful tool for characterizing minerals and identifying unique geological features. In many cases a complete analysis can take less than five minutes with no sample preparation. Micro-domains can be analyzed with a Raman microscope while bulk samples can be easily measured using an upward looking Raman system with automatic focusing, exposure and fluorescence correction.
