Abstract
An instrument that selectively counts, according to size, aerosol particles containing certain specific metals is described. The technique employed is based on the principle of spectrothermal emission of individual particles passing through the combustion zone of a hydrogen‐air flame. After the flash of light from each emitting particle passes through a monochromator, it is converted to a voltage pulse which is electronically counted according to height. The instrument sensitivity was determined for aerosols of NaCl, CaCl, CaO, Fe2O3, KOH, LiOH, MnO2, and MgO. The minimum size particle detectable varied from 0.10μ diam for NaCl to 1.22μ diam for MgO.This publication has 1 reference indexed in Scilit:
