Purity of Natural Monoisotopic Substances.

Abstract—: In this paper, we discuss general aspects of the impurity composition of natural monoisotopic substances, which are exemplified by samples in the Permanent Exhibition-Collection of Extrapure Substances. The entire set of natural monoisotopes is divided into subsets belonging to sets of alkali and alkaline-earth metals, transition metals, rare-earth metals (REMs), and p-block elements. We estimate the average and total concentrations of elemental impurities in subsets of the purest samples of the natural monoisotopes. The purest monoisotopes are those of the p-block elements. Next are samples of the alkali and alkaline-earth metals, transition metals, and REMs. We estimate the contributions of individual impurity classes to the total impurity concentration, which enables more accurate characterization of the impurity composition of the natural monoisotopes and statistical characteristics of its description.
