Abstract

A method of vaporizing a multicomponent liquid, such as a hydrogen peroxide and water solution, for injection into a vacuum chamber including the steps of metering successive predetermined increments of the liquid at a predetermined rate onto a heated surface in a vaporization chamber. Upon exposure to the heated surface, each liquid increment is substantially instantaneously vaporized before the next succeeding liquid increment is metered onto the heated surface to produce a multi-component vapor increment having substantially the same weight percent composition as the multicomponent liquid increment. Each vapor increment is passed into the vacuum chamber.
