Identification and Quantitative Measurements of Chemical Species by Mass Spectrometry
AUTHOR | Administration (Nasa), National Aeronaut |
PUBLISHER | Independently Published (08/21/2020) |
PRODUCT TYPE | Paperback (Paperback) |
Description
The development of a miniature gas chromatograph/mass spectrometer system for the measurement of chemical species of interest to combustion is described. The completed system is a fully-contained, automated instrument consisting of a sampling inlet, a small-scale gas chromatograph, a miniature, quadrupole mass spectrometer, vacuum pumps, and software. A pair of computer-driven valves controls the gas sampling and introduction to the chromatographic column. The column has a stainless steel exterior and a silica interior, and contains an adsorbent of that is used to separate organic species. The detection system is based on a quadrupole mass spectrometer consisting of a micropole array, electrometer, and a computer interface. The vacuum system has two miniature pumps to maintain the low pressure needed for the mass spectrometer. A laptop computer uses custom software to control the entire system and collect the data. In a laboratory demonstration, the system separated calibration mixtures containing 1000 ppm of alkanes and alkenes. Zondlo, Mark A. and Bomse, David S. Glenn Research Center NASA/CR-2005-213820, E-15178 NAS3-01164; WBS 22-101-42-02
