Compositions, methods, devices, and systems for purifying a source liquid from a replenishment stock solution that includes stabilizing agents, such as metal ions, prior to vaporization. Certain embodiments effect the purification with a solid perfluoronated ionomer, such as a perfluoronated ionomer membrane. Advantageously, source liquids purified in this manner provide feed stocks for production of ultra-pure gaseous reagents. As well, performance characteristics of membrane-based vaporizers relying on transport processes are improved.

A method and chemical delivery system are provided. The method includes providing a non-aqueous hydrogen peroxide solution having a vapor phase separated from the substantially non-aqueous hydrogen peroxide solution by a membrane. The method further includes contacting a carrier gas or vacuum with the vapor phase and delivering a gas stream comprising hydrogen peroxide to a critical process or application. The chemical delivery system includes a non-aqueous hydrogen peroxide solution having a vapor phase separated from the substantially non-aqueous hydrogen peroxide solution by a membrane. The system further includes a carrier gas or vacuum in fluid contact with the vapor phase and an apparatus for delivering a gas stream comprising at least one component of the hydrogen peroxide solution to a critical process or application.
