  • Test kit for the quantitative determination of narcotic drugs
    Patent number: 9347961
    Abstract: A test kit for the quantitative determination of narcotic drugs comprising (A) series of sealed vessels, each vessel containing a deuterium free isotopologue of a narcotic drug in exactly defined concentrations and quantities, wherein the isotopologue differs from vessel to vessel and—wherein the quantities of the isotopologue differ from vessel to vessel or are the same for all vessels; and/or (B) series of sealed vessels, each vessel containing in exactly defined concentrations and quantities the same isotopologue in quantities which differ from vessel to vessel; wherein the free isotopologues are selected from narcotic drugs; prodrugs, salts, solvates, hydrates and polymorphs and contain at least three stable isotopes selected from the group consisting of 13C, 15N and 18O in the molecule with a degree of labeling of at least 95 mol-%; the use of the test kit and a method for quantitatively determining narcotic drugs.
