For that you need to examine the vapour given off by the urine. Analysis of the vapour using gas chromatography revealed four compounds. The strongest smelling are methanethiol and dimethyl sulphide which smell like old cabbage. There are also two compounds which might give the odour that tinge of sweetness.
