Abstract
A diffusion diluter is described and a method for using such apparatus with a condensation nucleus counter, wherein a particle containing reactive gas is diluted with an inert diluent gas to diminish the reactive character of the particle-containing gas without disturbing the particle concentration of the gas allowing it to be accurately and safely measured for its particle content.
