MASS SPECTROMETER STUDY OF METAL-CONTAINING FLAMES
Abstract
Studies with an aerodynamic molecular beam sampling system at 0.1 to 5 atmospheres show that the shape of the second orifice (skimmer) is unimportant when beam densities are low at the skimmer. With higher densities a blunt skimmer reduces polymer formation and increases mass separation effects. The drop-off in beam intensity with increasing orifice-to-skimmer distance does not disagree with the normal molecular beam scattering dependence. Changes and improvements in the sampling system to facilitate work with flames containing condensible species are described.
