Identification of beta-carotene in an evaporitic matrix-evaluation of Raman spectroscopic analysis for astrobiological research on Mars

Original language description

In this paper, Raman microspectrometry was tested as a nondestructive method of determining the lowest detectable ?-carotene content in experimentally prepared evaporitic matrices?namely, gypsum, halite and epsomite. Two excitation wavelengths were compared?514.5 and 785 nm, ?-carotene signals at the 0.1 to 10 mg kg?1 level?the number of registered ?-carotene Raman bands differed depending on the particular mineral matrix and the excitation wavelength. Concentrations of ?-carotene of about one order ofmagnitude higher were identified when analysed through single crystals of gypsum and epsomite, respectively.
