METHOD OF DETERMINING THE CONCENTRATION OF AN ELEMENT IN A SOLID USING RELATIVE ABUNDANCES OF ISOTOPES FROM THE SOLID AND A REFERENCE SOLID

摘要

A method of determining the concentration of an element of interest in a solid of interest based on the ratio of the measured relative abundances of two isotopes in the solid of interest, one isotope of the element of interest and the second isotope from an element represented in the chemical formula of the solid of interest, and comparing this ratio to the ratio of the measured relative abundances of the same two isotopes for a reference solid for which the concentration of the element of interest is known. A method of calculating the concentration of the element of interest in the solid of interest. A method of executing a computer software program with instructions for calculating the concentration of the element of interest in the solid of interest.

1. A method of determining the concentration of an element of interest in a solid of interest comprising the steps of: obtaining a measurement of the relative abundance of an isotope of the element of interest in the solid of interest; obtaining a measurement of the relative abundance of an isotope of the element of interest in a reference solid possessing the same nominal crystal structure as the solid of interest; comparing the measurement of the relative abundance of an isotope of the element of interest in the solid of interest to the measurement of the relative abundance of an isotope of the element of interest in the reference solid; calculating the concentration of the element of interest in the solid of interest.
