An application of a space technique for pollution detection.
Abstract
Description of the hazardous gas detection system (HGDS) used during Apollo-Saturn launch tests for identifying and analyzing extremely minute amounts of gases escaping during cryogenic loading. These gases included hydrogen, helium, nitrogen, oxygen, nitrogen tetroxide, and hydrazine N2H3 radical. The heart of the HGDS is a mass spectrometer operating under high vacuum and capable to measure both qualitatively and quantitatively the presence and percentage of any gas whose molecular weight is between 2 and 150 atomic mass units. It is suggested that such a system could be utilized to detect environmental pollutants.
