1. A method of detecting the presence of vicinal polyhydroxyl compounds in a solvent, comprising the steps of:

  • a. establishing the emission characteristics, as a function of polyhydroxyl-compound concentration, of a dye compound comprising a binding moiety selected from the group consisting of boronic acid, boronate ion, arsenious acid, arsenite ion, telluric acid, tellurate ion, germanic acid and germanic ion, covalently linked to a chemical group such that the compound exhibits the properties of a fluorescent dye and wherein binding of said compound to a compound containing vicinal hydroxyl groups results in quantitative attenuation of dye properties;

    b. contacting said solvent with a sample carrier;

    c. introducing said dye into said solvent;

    d. without removing the unbound dye, determining the concentration of polyhydroxyl compound by measuring at least one characteristic of the emitted radiation, the characteristic being selected from the intensity and wavelength.
