X-ray diffraction, electron-probe microanalysis and the infrared reflectivity studies have been performed on the Hg1-xCoxSe samples corresponding to the nominal crystal compositions 0 =< x =< 0.05. it was shown that the "HgSe-like" TO photon frequency measurements can serve as a sensitive tool in order to determine the mixed crystal composition.
