Abstract:
1. A method for determining efficiency of a vaporizer for a vaporization process, the method comprising the steps of: storing a plurality of first data values in a memory, wherein said first data values are indicative of an electrical property of a capacitor in response to a plurality of predetermined concentrations of hydrogen peroxide in a liquid decontaminate, exposing a first sensor, having a capacitor, to the liquid decontaminate including hydrogen peroxide, wherein the electrical property of the capacitor is used to generate a first signal indicative of the concentration of hydrogen peroxide in the liquid decontaminate before vaporization by a vaporizer; vaporizing the liquid to produce a gas including a vaporized decontaminate; and exposing a second sensor to the gas, wherein the second sensor generates a second signal indicative of the concentration of vaporized hydrogen peroxide in the vaporized decontaminate; determining concentration of hydrogen peroxide in the liquid decontaminate (X determining concentration of the vaporied hydrogen peroxide (X determining actual vaporization efficiency (E
