Abstract (en)

[origin: WO02053248A1] The invention concerns a method and a device for forming by evaporation a volatile substance comprising at least a predetermined number of elementary constituents, wherein are provided means (205) for circulating in parallel fluxes of a gas controlled or regulated in flow rate through receptacles containing each at least an elementary constituent to be evaporated, and means (208) for the mixing gas streams loaded with evaporated constituents derived from said receptacles, so as to obtain an output gas stream containing predetermined or controlled concentrations of said evaporated constituents.
