Abstract: A process wherein outgassing rates of volatile organic compounds (VOCs) in an object, particularly habitable vehicles, are accelerated by placing the subject object in a vacuum chamber and placing heat sources either inside the object being treated, outside the object, or both. The process includes measuring and monitoring the temperature of selected surfaces inside the object being treated. The heat sources are adjusted to maintain a temperature which is safe for the materials and which will promote maximum outgassing rates. During the treatment process, while a vacuum and heat are being applied to the subject object, the gasses in the chamber are monitored for both their composition and quantity. When the outgassing rates of the VOCs reach acceptable levels, the process cycle is terminated. The vacuum in the chamber is broken to restore atmospheric pressure, and the object being treated is removed from the chamber.

Abstract: A method which enhances a disinfection process by using a catalyst which increases in effective surface area during the process. Also disclosed are contact lens disinfecting systems which are designed to maintain a high concentration of hydrogen peroxide solution for a longer period of time before increasing the overall surface area of catalyst exposed to the hydrogen peroxide solution. The devices utilize pressure from expanding oxygen generated within the system through use of a small catalyst, or through exposure of only a small portion of a large catalyst, to control deployment of the large catalyst for completing disproportionation of the hydrogen peroxide.
