DETERMINING THE GEOGRAPHIC ORIGIN OF METALS |
| 摘要 |
A method of determining the geographic origin of a metal can comprise measuring a first isotope and a second isotope of the metal by high-resolution mass spectrometry; calculating a ratio of the first isotope and the second isotope; comparing the ratio to native ratios of isotopes of the metal of native samples from a plurality of geographic locations using a database; and matching the ratio to a geographic location. |

1. A method of determining the geographic origin of a metal in a sample, comprising:
measuring a first isotope and a second isotope of the metal by high-resolution mass spectrometry; calculating a ratio of the first isotope and the second isotope; comparing the ratio to native ratios of isotopes of the metal of native samples from a plurality of geographic locations using a database; and matching the ratio to a geographic location. |
