MASS SPECTROMETER STUDY OF METAL-CONTAINING FLAMES

Abstract

Addtional improvements in orifice sizes and spacings have made possible molecular beams from 1 atm. sources of approximately 1 x 10 to the 17th power molecules/sq cm sec t the collimating or thrd slit. With such a beam we can easily detect one part in 10 to the 5th power with present mass spectrometer sensitivity. The beam reflects highly ordered motion from the first orifice with no evidence of shock formation at the skimmer or second orifice. This sampling system is capable of quenching large quantities of N2O4 from 1 atm. N2O4 equilibrium NO2 and is currently being applied to the sampling of the burnt gases of smple flames. (Author)
