3 Terms and definitions
GB/T 32267-2015, GB/T 34826-2017, JJF1005-2016 defined and the following terms and definitions apply to this file.
3.1 Isotope
Different atoms of the same element with the same number of protons, different numbers of neutrons (or different mass numbers).
3.2 Isotope ratio
The number of moles of two isotopes (3.1), or the number of atoms, or the number of ions.
3.3 Isotope abundance
The percentage (%) of the isotope (3.1) atom in the total number of atoms of the element.
Note. Rewrite GB/T 32267-2015, definition 4.10.
3.4 Isotope composition isotopic composition
The proportion of each isotope (3.1) in an element expressed in atomic percent, and their sum is equal to 1.
Note 1. The isotope composition can be expressed in abundance and can also be expressed as a ratio or a delta value.
Note 2. The delta value refers to the relative difference between the isotope ratio of the sample given by mass spectrometry and the ratio of the standard sample, which can be expressed in thousands of steps ( per thousand).
3.5 Concentrated isotope
Isotope (3.1) material obtained by enrichment.
Example. Commonly used enrichment methods include gas diffusion method, electromagnetic separation method, and the like.
