Dehydration rate of the glycine-MgSO4·5H2O complex and the stability of glycine expelled from the complex by in situ Raman spectroscopy under Mars-relevant conditions

In this work, we studied the dehydration process of the glycine-MgSO4·5H2O complex under Mars-relevant conditions (99% CO2 and 0.6% H2O under ultra violet (UV) irradiation exposure at 7-mbar pressure and high vacuum conditions: 8 × 10−5 and 5 × 10−5 mbar) by in situ Raman spectroscopy inside a plane...
