Chemical imaging with a spaceflight LDMS instrument for planetary exploration

Oya Kawashima, Ricardo Arevalo, Lucas T. Andrews, Madeline C. Raith et autres

One of the analytical advantages of Laser desorption/ablation mass spectrometry (LDMS) is its potential for spatially-resolved composition analysis of solid samples, supporting 2D chemical mapping and/or 3D depth profiling as ions are generated within a focused laser beam footprint. In this study, …

Detection of Short Peptides as Putative Biosignatures of Psychrophiles via Laser Desorption Mass Spectrometry

Ziqin Ni, Ricardo Arévalo, A. Bardyn, Lori Willhite et autres

Studies of psychrophilic life on Earth provide chemical clues as to how extraterrestrial life could maintain viability in cryogenic environments. If living systems in ocean worlds ( e.g., Enceladus) share a similar set of 3-mer and 4-mer peptides to the psychrophile Colwellia …
