Diffusion method for generating known concentrations of vapor.
Evaluation of direct reading colorimetric gas detecting devices. Kusnetz HL, ed. Cincinnati, OH: Public Health Service, 1962 Jan; :23-32
Design characteristics and theoretical principles are given for a gas generator for producing low concentrations of vapors. The generator is based on the diffusion properties of vapors and gases, and is an adaptation of the Fortuin gas generator extending the application of the generator to include the vapors of liquids with high vapor pressures as well as low vapor pressures.
