An atomizeratomizes a multi-component liquid from a reservoirinto a cloudcomprising small dropletswhich are ejected into the atmosphere to a certain height and allowed to fall toward a surface. Essentially complete evaporation is assured by maintaining the size of the droplets, the liquid's component vapor pressures and the height through which the droplets fall according to a predetermined relationship. Also, the suitability of a liquid for evaporation in a vibrating plate atomizer is determined by measuring the rate of size decrease and the surface tension of a pendant drop of the liquid after a predetermined amount of the liquid has evaporated from the drop.
