Abstract
The present invention relates to an apparatus and methods for the identification or authentication of liquid products by the addition of an anti-Stokes marker. The invention features an apparatus and method for the identification of a liquid, dynamic or static, that includes adding an anti-Stokes luminescent marker compound to the liquid followed by exposing the compound to a light source of a known wavelength or known wavelengths and then detecting one or more shorter wavelength emissions from the marker, where the identity of the liquid is confirmed by the emission wavelength or wavelengths that are detected and quantified. The irradiating source of light includes, but is not limited to, a laser and other conventional light sources.
