MASS SPECTROMETER STUDY OF METALCONTAINING FLAMES

Abstract

Cyanogen-oxygen flames have been sampled at one atmosphere at temperatures such that the 02 and C02 are largely dissociated. Addition of TiC14 to such flames has allowed the observation of TiO(+) and C1(+) but under conditions which suggest that they arise largely from TiOC1(g) transpired from the oxide deposited on the cold probe. A study of beam formation from cones with apex angles from 90 degrees to 30 degrees was made. Serious intensity attenuation was observed with angles sharper than 60 degrees. Sharpedged, 90 degrees, cooled, stainless steel cones, 1/2-in. long, produced strong beams, and it was possible to probe the reaction zones of lean, CH4-02, 1/20 atmosphere flames without serious disturbance. Preliminary profiles through such flames, with and without CH3Br inhibitor, are discussed.
