TOF-on-a-flange, in W. B. Brinckerhoff (JHU/APL) et al. 5 th Workshop on Harsh Environment Mass Spectrometry, September 22, 2005
Sample Handling and Vacuum Stuff High-resolution in situ chemical imaging • xyz sample manipulation system developed in collaboration with Honeybee Robotics • examine location of organics in meteorites Other Honeybee Robotics Collaborations • MSL Sample Acquisition/Sample Handling and Processing (SA/SPaH) system • Precision subsampling systems Vacuum Issues (Mars) • Method 1: (“brute force”) Acquire samples; use vacuum seals/valves; pump out. • Method 2: (“relax requirements”) Sample and/or ionize at ambient pressure; draw into dynamically-pumped MS; consider designs that tolerate higher operating pressure. • Evaluating current generation of Creare mini TMD pumps (to be flown in SAM on MSL) W.
