FIELD: test equipment. SUBSTANCE: spectra of combination scattering and radiation of analyzed and chirality-pure specimen are detected at the second optical harmonic frequency. Availability and contents of impurity in heterogeneous phase of chirality-pure specimens are judged from relation of measured intensities. EFFECT: improved precision. 1 tbl, 3 dwg
