MASS SPECTROMETER STUDY OF METAL-CONTAINING FLAMES

Abstract

Additional free radical sampling from sheathed H2-O2 flames gave O and OH concentration agreeing with previous studies on a simple torch burner. A change in beam modulation frequency from 10 cps to 52 cps gave essentially unchanged sampling behavior. It was determined that beam signals could be measured in the presenae of a background of up to 1,000 times the beam intensity. Initial studies on the Fe-O and Fe-O-H systems have failed to yield any gaseous iron-containing species, although orifice plugging rates and sensitivities indicate thhey should be observed. The species S, SH, and SO have been observed in anomalous ratios when H2S was added to lean and rich H2-O2 flames.
