As such, S.A.M. will continuously sample concentrations of major air constituents (CH4, H2O, N2, O2, and CO2) and report results in two-second intervals. The S.A.M. is a technology demonstration planned to be delivered in February 2019 and consequently launched in May 2019. The S.A.M. 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 S.A.M. instrument will provide on-demand reporting on trace volatile organic compounds (VOC) at ppm to ppb levels of 21+ species relevant for astronaut health. Here we are reporting on the results from the Development Model (DM) as its being prepared to be deliver to Marshal Space Center for testing and validation.engMass SpectrometryGas ChromatographyMicro-Electro-Mechanical SystemPresentation
