Abstract

A method of using a tracer to determine the occurrence of dilution and/or to verify the source of a refrigeration/heating fluid, comprising: combining up to 1000 ppm of a tracer, said tracer being analytically detectable and selected from the group consisting of hydrofluorocarbons, deuterated hydrofluorocarbons, deuterated hydrocarbons, perfluorocarbons, fluoroethers, brominated compounds, iodated compounds, nitrous oxide and combinations thereof, with said refrigeration/heating fluid to form a tracer-containing composition, with the proviso that said refrigeration/heating fluid is different from said tracer and comprises a hydrofluorocarbon, hydrochlorofluorocarbon, perfluorocarbon, fluorocarbon ether, carbon dioxide, ammonia or mixture thereof; detecting the presence of said tracer; andwhen the source is being verified, verifying that the tracer detected corresponds to the tracer combined with said refrigeration/heating fluid; and when dilution is being determined, determining that the tracer detected is present in a lesser quantity than originally added to said refrigeration/heating fluid.
