Abstract

International Space Station crew members face the unique challenge of maintaining air quality due to the volatile organic compounds (VOCs) that have the potential to accumulate at unsafe levels. The Spacecraft Atmosphere Monitor (SAM) is a miniature gas chromatograph/mass spectrometer (GCMS) designed to measure major constituents (such as N2, O2 and CO2) and trace VOCs within the cabin of the spacecraft. The gas chromatograph is responsible for separating the sample into its components in order to be characterized. The oven of the gas chromatograph must reach a temperature of 150°C in order to heat constituents of the analyte into the gas phase. The heater was tested to determine the proper operating parameters. An appropriate operating point was found to adequately heat the oven of the GC. Further work to determine the proper operating parameters of the preconcentrator (PC), a component of the instrument for adequate peak separation, should be done, leading to the improvement of the GCMS instrument for SAM.
