Raman spectra of pure biomolecules obtained using a handheld instrument under cold high-altitude conditions
2010
Abstract
A handheld Raman spectrometer (Ahura First Defender) was tested for the unambiguous identification of biomolecules (pure amino acids, carboxylic acids, saccharides and trehalose) in the solid state under outdoor conditions (including moderate climate conditions as well as cold temperatures and high altitudes). Repetitive measurements carried out under identical instrumental setups confirmed the excellent reliability of the Raman spectrometer.
Raman bands are found at correct wavenumbers +/-3 cm(-1) compared with reference values.
