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 13 C, 15 N and 18 O 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.
Abstract:
The present invention is directed to poly- and perfluoroalkyl sulfonic acids and poly- and perfluoroalkyl acids and processes for the purification and isolation of isomers from mixtures as well as highly pure poly- and perfluoroalkyl sulfonic acids and poly- and perfluoroalkyl acids and the corresponding uses.
Abstract:
Deuterium free, stable isotope labeled hallucinogens and/or stimulants containing a 2-phenylethylamine-based structural unit and containing at least three stable isotopes selected from the group consisting of 13 C, 15 N and 18 O as free bases and as their salts; method of their preparation and their use in the chemical analysis, in particular forensic chemical analysis, and in metabolic studies.
