  • Tracer and method of identifying tracer in product
    Patent number: 10267740
    Abstract: A method of detecting a tracer compound dissolved in a liquid composition via surface-enhanced spectroscopy includes the steps of: a. optionally, diluting the liquid composition or the separated liquid by mixing with a diluent liquid; b. bringing a sample of the separated liquid into contact with, a spectroscopy-enhancing surface including gold, silver or copper; c. obtaining a Raman spectrum from the sample; and d. calculating, from the spectrum, the concentration of the tracer in the sample relative to the concentration of a second component of the composition.
