ARPA Institute and Armenian Engineers and Scientists of America
present the Lecture/Seminar “An Avnaced Miniature Gas
Chromatograph-Mass Spectrometer System for Air and Water Quality
Measurements in Long Duration Human Flight” on Thursday, January 27,
2005 at 7:30 PM in the Merdinian School Auditorium. The presenter
is Dr. Ara Chutjian.
The address is 13330 Riverside Dr., Sherman Oaks, CA 91403.
Directios: On the 101 FY Exit on Woodman, Go North and Turn Right on
Riverside Dr.
Abstract: Any space mission involving extended astronaut travel time
must have an accompanying system for monitoring the quality of the
onboard air and water. The system must not only meet the detection
criteria for undesirable species, at the detection limits set by NASA
and the National Academy of Sciences; but must also meet generic
requirements, such as having low mass, volume, and power; requiring
minimal astronaut involvement, and having minimal need for
consumables. The criteria for acceptable air and water contamination
levels will be briefly reviewed. Some of the engineering physics
involved in a new, second-generation, miniature gas chromatograph-mass
spectrometer being proposed for the International Space Station will
then be discussed. And, finally, explanations of the GCMS operation,
with comparisons to methods currently in use aboard the ISS, will be
given.
1This work was carried out at JPL/Caltech, and was supported through
contract with NASA.
ARA CHUTJIAN: Dr. Chutjian is a Senior Research Scientist at the Jet
Propulsion Laboratory/Caltech; and Leader of the Atomic and Molecular
Collisions Group. He is also a Visiting Faculty Associate at the
California Institute of Technology. Dr. Chutjian received his PhD
from the Univ. California (Berkeley) in 1966. He served as a Research
Associate at the AT&T Bell Laboratories, and at USC. In 1969 he
joined JPL where he presently leads a group of researchers in the
areas of ultralow energy electron attachment, electron-highly charged
ion (HCI) collisions, HCI-neutral charge-exchange and X-ray emission,
measurement of metastable HCI lifetimes, fast neutral-beam collisions,
trace-species detection, and miniaturization of mass spectrometers and
gas chromatographs for space flight. He is Principal Investigator on
the Trace Gas Analyzer, an astronaut hand-held miniature mass
spectrometer leak detector use for leak detection at the International
Space Station. He holds sixteen patents, and has over 150
publications in the refereed literature. He is a Fellow of the
American Physical Society and a recipient of NASA’s Exceptional
Scientific Achievement Medal for his work in ultralow energy electron
attachment, and the introduction of electron energy loss methods in
electron-ion collisions.
