Abstract
Systems and methods for measuring the isotope ratio of one or more gaseous oxides produced during combustion of drugs, pharmaceuticals, or medicines aiming to detect counterfeit drugs, pharmaceuticals, or medicines based on comparison of the isotopic composition of the tested drugs, pharmaceuticals, or medicines with the isotopic composition of the authentic products.
Claims14
A method of verifying authenticity of a product, the method comprising the steps of:
- a) forming a gaseous oxide through combustion of the product with a gas containing molecular oxygen;
- b) delivering a sample of a gas mixture containing the gaseous oxide to an isotopic ratio gas analyzer;
- c) measuring a value proportional to the ratio of a number of molecules of a first isotopologue of the oxide in the sample to a number of molecules of a second isotopologue of the gaseous oxide;
- d) submitting the measured value to a manufacture of the authentic product or to a third party for the product authenticity verification, wherein the product comprises at least one of a drug, a pharmaceutical, a vaccine, or a medicine, wherein the gaseous oxide selected from the group consisting of:
- CO, CO2, N2O, NO, NO2, H2O, H2O2, SO2, SO3, ClO.
