The article provides information on the ionometric method of analysis and the prospects for its development. The importance of developing permanence of the verification conditions of ion-selective electrodes is emphasized. An example of developing a mono-element solution for verifica-tion on the basis of a divalent calcium ion is given.

Key words: calcium ions, verification, ion-selective electrodes.
