Abstract
e measured the concentration of several gases in the smoke nerated by carbon dioxide laser applied to a piece of at. Gas sample was collected at several points close to an ission spot on the meat. The concentration analysis were ne dy means of Saltzman Reagent for NOx, infrared spectroopy for HCHO, and gas detector tube for CO, CO2, CH3COOH, I3NH, H2S and CH3SH. They are responsible for unpleasant or.
onsidering the present standards of ambient air pollution, e concentrations of NOx,CO and CO2 were low; that is, 1-0.05, 4-20 and 400ppm, respectively. Those of HCHO and I3COOH were relatively higher; showing 0.1-6ppm, respective. And that of CH3NH2 was very high level of several tens m. Among sulfur compounds figures of 1-4ppm for CH3SH and -2ppm for H2S were observed, but sulfur dioxide was not und.
n preliminary study was made on flying micro-particle in-uding tissue fragments and tar like material by thermal gradation of meat. And the efficiency of a gas scavenging stern which we designed for laser operation was also amined.
