Abstract
Abstract DETECTION OF LOCALIZED SOURCES OF OXYREACTIVE HYDROCARBONS EMITTED INTO AMBIENT GASES IS ACCOMPLISHED BY CONVERTING IN THE GAS THE EMITTED MOLECULARLY DISPERSE, NORMALLY NONDETECTABLE HYDROCARBONS INTO DETECTABLE PARTICULATES AND INSPECTING THE GAS FOR THE PRESENCE OR ABSENCE OF THESE PARTICULATES TO REVEAL THE PRESENCE OR ABSENCE OF SUCH HYDROCARBONS ON THE GAS. THIS INVENTION PROVIDES EXTREMELY SENSITIVE INDICATION OF SUCH LOCALIZED HYDROCARBON SOURCES AS SUBSURFACE OIL DEPOSITS, TRESPASSING PERSONNEL AND LEAKS IN FLUID CONTAINER WALLS.
