Obtaining Raman spectra of minerals and carbonaceous matter using a portable sequentially shifted excitation Raman spectrometer – a few examples

Abstract

We present examples of application of a recently developed portable sequentially shifted excitation Raman spectrometer for identifying three series minerals and carbonaceous matter. Those include compounds of relevance for the fields of geobiology and exobiology: sulfates and carbonates, organic minerals, and carbonaceous matter. It is demonstrated that unambiguous obtaining of Raman spectra can be achieved fast and with the gain in eliminating potential fluorescence features. Copyright © 2017 John Wiley & Sons, Ltd.
