“…Since this information is derived from the masses of the whole and different parts of the molecule it requires no previous knowledge, or very little, of the nature of the compound analyzed. A discussion of this point is given by Dr. Biemann in this report and additional information and data may be found elsewhere [Beynon, 1960;Reed, 1962;Elliott, 1963;McLafferty, 1963a, b;McDowell, 1963;Budzikiewicz et al, 1964a, b;Reese and Harllee, 1964], Potentialities of the Gas Chromotography-Mass Spectrometry (GC-MS) System for the Detection of Extraterrestrial Life* Typical Chemical Composition. Whereas the gas chromatographic-mass spectrometric system wiII not be able to "detect" life in any definitive way, * For simplification, "extraterrestrial life" is considered to have the same attributes as terrestrial life.…”
