The paper considers the possibility of determining the deviation from the stoichiometry in cadmium and zinc chalcogenides by the composition of the equilibrium vapor phase. The conditions for the evaporation are considered. It is shown that if the ratio of the of the solid and vapor phases volumes is more then 120, it is possible to determine the deviation from stoichiometry at the order of magnitude 1014 cm-3.
