Abstract

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. Abstract : A new portable sequentially shifted excitation Raman spectrometer allows obtaining excellent quality, fluorescence‐free Raman spectra of minerals in the range of 300–3200 cm −1 . First tests on specimens of amorphous carbons from metamorphic rocks, crystalline organic minerals, sulfates, and carbonates are given here. Comparison of performances with other portable Raman spectrometers is made, and future field use for geoscience and exobiology is suggested.
