Abstract: 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.

Abstract: Methods, systems, and devices for decontaminating materials containing biological or biologically derived materials, such as microorganisms or DNA products, are provided. The methods, systems, and devices may be used for decontaminating or sterilizing materials, such as surfaces, including, but not limited to reducing the number of viable microorganisms on surfaces. The methods, systems, and devices may further be used for rendering DNA non-amplifiable in nucleic acid amplification reactions that synthesize DNA amplification products.

Abstract: A method and chemical delivery system are provided. The method includes providing a concentrated aqueous hydrogen peroxide solution in a boiler having a head space, boiling the concentrated aqueous hydrogen peroxide solution to produce a dilute vapor comprising hydrogen peroxide within the head space of the boiler, and adding a dilute aqueous hydrogen peroxide solution to the concentrated aqueous hydrogen peroxide solution within the boiler to maintain the concentration of the aqueous hydrogen peroxide solution in the boiler. The method further includes delivering the dilute vapor comprising hydrogen peroxide to a critical process or application.
