- Abstract
- Smoke particles produced by a laminar diffusion flame with acetylene fuel have been characterized according to there size, structure, and chemical composition. Particle size and structural measurements were obtained by transmission electron and optical microscopy. The smoke generator is capable of producing mono-sized particles 7 to 10 nm in diameter, and soot agglomerates containing 10(2)-10(6) small (20 to 30 nm) primary particles. Chemical composition was investigated by elemental analysis (C,H) and by laser microprobe mass spectrometry (LAMMS).
