Abstract:
1. A method for tracing, surveying, monitoring, and/or measuring the movement of aqueous fluids in aqueous and/or non-aqueous media, comprising the addition of one or more chemical compound(s) selected from biphenylmono- and polysulphonic acids and salts thereof, fluorenemono- and polysulphonic acids and salts thereof, and p-terphenylmono- and polysulphonic acids and salts thereof into said aqueous fluids, wherein the chemical compound(s) is detected in said aqueous or non-aqueous media through analysis using analytical techniques such as high performance liquid chromatography with fluorescence detection and/or liquid chromatography-electrospray mass spectrometry such that the movement of said chemical compound(s) are traced, surveyed, monitored, and/or measured in said aqueous or non-aqueous media.
