Applicant (11:30 am) Application of Ion Mobility Mass Spectrometry imaging of complex molecular surfaces for potential future Lunar Mars environments

Monday, June 18, 2018

Abstract: The imaging of molecular features on a planetary environment could be accomplished through the use of ion-mobility and/or ion-funnel mass spectrometry. The mid-range operational pressure, with the potential for tuning ion flow through various gas compositions provides a unique opportunity to dial in a set of ion-optical parameters that would allow for both miniaturization and high-speed imaging. The added application of a second post-ionizing laser system that decouples the desorption event from an ionization event provides a gentle handle from which to preserve larger molecular fragments and thereby reduce the data analysis complexity. Under current development are several smaller footprint ion-detection systems as well as a Lunar Mars Planetary Chamber at Johnson Space Center ARES in Houston. The ‘LuMa’ system has a wide parameter space that aims to dial-in to a wide variety of planetary bodies allowing for positioning the novel instrumentation sets right next to the curated samples at the Astromaterials laboratory
