Elemental Impurity Composition of High-Purity Volatile Hydrides and Chlorides

Аннотация

We have calculated the total elemental composition and assessed its statistical characteristics for two classes of high-purity volatile substances—inorganic hydrides and chlorides—using Exhibition–Collection of Extrapure Substances data. The average and total contents of elemental impurities in the purest samples of compounds of these classes have been estimated. Using the division of elemental impurities into classes, we have estimated the contributions of individual classes to the total impurity content in arrays of hydride and chloride samples. The use of these calculation techniques makes it possible to more accurately characterize the impurity composition of individual samples and arrays of samples on the whole, refining statistical characteristics of the description of the impurity composition.
