Simcic, California Institute of Technology, Jet Propulsion Laboratory, USAThe Spacecraft Atmosphere Monitor (SAM) is a miniature gas chromatograph mass spectrometer (GCMS) intended for assessing trace volatile organic compounds and the major constituents in the atmosphere of present and future crewed spacecraft. As such, SAM will continuously sample concentrations of major air constituents (CH4, H2O, N2, O2, and CO2) and report results in two-second intervals. The SAM is a technology demonstration planned to launch in Feb 2018 and we report here on recent developments taking place in preparation for building an engineering model of the instrument. We have demonstrated successful micro-electro-mechanical system (MEMS) GC injection and its coupling to a quadrupole ion trap mass spectrometer (QITMS). The SAM is mechanically designed to operate under hi-G loads present during launch events and can operate at sub-atmospheric pressures relevant to extra-vehicular activities. Total instrument mass is projected at 9.5 kg with power consumption estimated at 35 W. The SAM instrument will provide on-demand reporting on trace volatile organic compounds (VOC) at ppm to ppb levels of 40+ species relevant for astronaut health.application/pdfenggas chromatographmass spectrometervolatile organic compoundsmicro-electro-mechanical systemquadrupole ion trapPresentation
