The quality of the vapour gas nucleation has been increased substantially in 1980 th. In addition to the all known for that time experimental techniques the Flow Diffusion Chamber (FDC) was developed. Several articles devoted to FDC were published in Russian scientific journals beginning 1978 [Anisimov and co-workers (1978a,b), etc]. The scheme of FDC involves using the hot laminar vapor-gas flow within the colder boundaries which is similar, for example, to D. Sinclair and V.K. LaMer generator

... of monodispersed particles. The current FDC scheme can be used for the vapor nucleation rate measurements at the total pressures from 0.3 to 3.0 Atm. FDC has been reproduced in Finland, USA, Japan, Czech Republic, Germany, Austria, and in several research groups at other countries. A conceptual problem in vapor nucleation is its treatment as a single component problem. In general, one should consider the carrier gas-vapor nucleation as a binary nucleation. In order to test the behaviour of an experimental setup , it is useful to have a standard system that can be measured over a range of typically employed nucleation conditions. The current state of Vapor-Gas nucleation rate measurements is published recently by Anisimov et al. (2009)
