[A generator for producing multicomponent organic solvent vapor in inhalation chambers].

A vapor generator for multicomponent organic solvents was developed and its performance was investigated experimentally. The vapors were generated from the surface of a sintered sphere of glass beads containing the organic solvents. The solvents were automatically supplied from the solvent reservoir to the sphere by suction pressure caused by the evaporation of the solvents and the generated vapors kept at constant high concentration over a long period. The vapor concentration increased with the decreasing flow rate and the increasing gas temperature. The concentration ratio of the generated vapor was found to be equivalent to the mixing ratio of solvents in the reservoir, so this device can generate multicomponent organic solvent vapors at any concentration ratio. The vapor generator is simple to construct and is recognized to be useful for investigation of inhalation toxicities of multicomponent organic solvent vapors.
