| abstract | A system for the verification of an aqueous urea solution suitable for use in a process for the selective catalytic reduction of nitrogen oxides emitted from a diesel engine mounted in a vehicle, said aqueous urea solution comprising from 30 - 35% of urea comprises a) a tracer composition comprising a first tracer compound, optionally at least one secondary tracer compound and optionally a solvent, the tracer composition being soluble in said aqueous urea solution b) analytical apparatus adapted to measure the concentration of said first tracer compound in a sample of said urea solution and compare said concentration with the concentration of tracer in a standard sample of urea solution containing a pre-determined amount of said first tracer compound said analytical apparatus being mounted on or within said vehicle, and c) an indicating means for indicating when the difference between the concentration of said first tracer in the urea solution and the concentration of tracer in the standard sample of the urea solution exceeds a pre-determined value. |
