Conclusions
Diffusion chambers with porous partitions can be recommended for batching vapors of liquids in air. They provide a stable operating condition and are suitable for obtaining considerably higher concentrations of vapor in air (gas) than those obtainable with batchers of other designs. They also serve to obtain given vapor concentrations in air (gas) from different liquids by computations from the data of the batcher's operating conditions and the physicochemical characteristics of liquids. The instrument constant is determined by the geometrical characteristics of the chamber and is found experimentally for different liquids. It can be established as a reliable physical quantity with an error of 2% which includes the error of the selected liquids' physical characteristics (D, p0) provided in reference books.
