    摘要: Apparatus and processes are presented to contact a dry, preferably high purity inert gas with a chemical composition in a pressure vessel, or a wetting composition, to form a wet inert gas, which is then used to pressurize the chemical composition out of the pressure vessel. No additional space is needed for an external humidifier. Since a very small amount of vapor is needed to form a wet inert gas, the composition of chemical composition will not be significantly affected.

    摘要: An apparatus and method for holding a solid precursor in a sublimator such that the solid precursor can be vaporized for saturating a carrier gas. The apparatus may include alternating disks or shelves that form inner and outer passages, as well as spaces between the disks for fluidicly coupling the passages to create a winding, tortuous fluid flow path through the sublimator for optimizing solid vapor saturation. The method may include directing a carrier gas into a sublimation chamber, around the first shelf in the outer passage, over the first shelf in the space, around the second shelf in the inner passage, and back out of the sublimation chamber.
