The monographs contain general information about the properties of elements and their compounds. Then chemical reactions are considered, which are the basis for analytical methods .. Methods as physical , physico-chemical and chemical , are described in relation to the quantification of this chemical element, from raw material analysis, hereinafter - typical semi-products of production and , Finally, end products - metals or alloys , Oxide, salts and other compounds and materials. Generally, the principles of definition are given and, where necessary, an accurate description of the entire process of definition is given. The necessary attention is paid to rapid methods of analysis. An independent place is occupied by the presentation of methods for determining the so-called impurity elements in pure materials ..
