Abstract

We are able to produce a narrowly distributed combustion aerosol with a mean particle size of about 10 nm by operating a laminar diffusion burner with acetylene fuel in the nominal "presooting" condition. Number concentrations of approximately 106 particles/cm3 are obtained. The mean particle size obtained by transmission electron microscopy (TEM) and by diffusion battery (DB) is 7 nm and 10 nm, respectively. Both measurements indicate a narrow size distribution with a geometric standard deviation of less than 1.4. Laser microprobe mass spectroscopy (LAMMS) indicates that the particles are composed of phosphorous and sulfur compounds, arising from acetylene fuel impurities, in addition to carbonaceous material.
