Application Note: Confocal Raman Imaging, Correlative Raman-SEM, and Atomic Force Microscopy: Geo-Science Applications
28 February 2019
Raman spectroscopy has long been applied in geoscience, for example for the identification and characterization of minerals, or in the observation of mineral phase transitions in high- and ultra-high pressure/ temperature experiments. By means of confocal Raman imaging (CRI), such characteristics can be evaluated from large-area scans on the centimeter scale to the detailed investigations with sub-micron resolution. In this study, WITec confocal Raman microscopes of the alpha300 and alpha500 series were used in order to carry out high-sensitivity measurements on a sample of diorite.
