3 terms and units of measure
3.1 Isotope abundance isotopebundance
The atomic share of the various isotopes possessed by an element in the element. Isotope abundance representation
There are. (1) atomic fraction. the number of moles of a certain stable isotope and the total number of moles of the element
Ratio; (2) atomic percentage. the atomic fraction expressed in percentage.
3.2 isotope abundance ratio isotopicabundanceratio
The ratio of the isotopic abundance of an element to the other isotopic abundance of that element.
3.3 δ value δvalue
The specific isotope abundance ratio of two specific isotopic abundances of a certain element of the sample to be compared with their standard sample isotope abundance
Poor, except for the ratio of the latter, dimensionless. The delta value is expressed in thousands of fractions, namely.
δ=Ru-RsRs ×10
3‰ (1)
Where. Ru---the ratio of the abundance of a particular isotope of an element of a sample to the maximum isotope of the element;
Rs---the isotope abundance ratio corresponding to the sample to be tested in the standard.
3.4 Mass range massrange
The mass range represents the interval from the smallest to the largest mass of the mass spectrometer that can be measured by the mass spectrometer. The unit is the atomic mass list.

3.5 resolution resolution
Resolution Characterization The ability of a mass spectrometer to identify tw
