One method which can be used to do accurate chemical analysis in the p.p.m. range, and often well below, is that of isotopic dilution in which a tracer isotope is used as an in ternal standard. Of course, the fact that it is eminently suited to sub p.p.m.
WebJul 26, 2024 · Linear mixing models are used to partition two sources with a single isotopic signature (e.g., δ 13 C) or three sources with a second isotopic signature (e.g., δ 15 N). The user supplies the mean, standard deviation, and number of samples from each of the source and mixture populations for each isotopic signature.
Isotope analysis is the identification of isotopic signature, abundance of certain stable isotopes of chemical elements within organic and inorganic compounds.
