摘要： A method of tracing an aqueous liquid, particularly an aqueous urea used for addition to a selective catalytic reduction system to remove NOx from diesel exhaust, includes adding a tracer comprising a pre-determined amount of a phenol to the liquid. The liquid can subsequently be identified by reacting a sample with a reagent containing a predetermined amount of 4-aminoantipyrine in the presence of an initiating compound such that the reaction between the reagent and a phenol in the liquid produces a chromophore and measuring the absorbance of the resulting solution of the chromophore.

摘要： A method of monitoring the flow of fluid within or from an oil or gas reservoir includes inserting a solid tracer into the reservoir. The tracer comprises at least one metal selected from caesium, niobium, tantalum, tellurium, terbium, lanthanum, gold, iridium, osmium, silver, platinum, palladium, rhenium, ruthenium, rhodium, hafnium, indium, a metal of the Lanthanide series of the periodic table, or a salt thereof. A sample of fluid within or flowing from the reservoir is collected and analysed to determine the amount of the tracer contained in the sample. A perforation tool allows for insertion of the tracer within the formation.

摘要： A method of identifying a product comprises forming a tagged product by adding to said product a tracer material comprising at least one tracer compound which is acceptable for use as an additive in food and subsequently analyzing a sample of said product to determine the presence of said tracer compound thereby to determine whether said sample is a sample of the tagged product. The method is especially useful for the identification of vegetable oil products from sustainably managed sources. The use of permitted food additives as tracers enables the product to be identified in the supply chain while also allowing it to be used safely in foodstuffs if required.
