Patent ID: 7829345

Claim:
A method for detection of a peroxide-based compound, the method comprising: directing ultraviolet light from an ultraviolet light source toward a location remote from the ultraviolet light source including the following steps: directing a first beam of ultraviolet light at a first wavelength to induce photodissociation of the peroxide-based compound into fragments including hydrogen peroxide; directing a second beam of ultraviolet light at a second wavelength to induce photolysis of hydrogen peroxide to hydroxyl radicals; and directing a third beam of ultraviolet light at a third wavelength to excite the hydroxyl radicals so as to emit fluorescence; capturing any fluorescence from the remote location that has been emitted by the excited hydroxyl radicals; and analyzing the fluorescence that has been captured from the remote location to determine the presence of the peroxide-based compound at the remote location.
