| abstract |
The invention relates to a method for identifying properties of substances, in particular liquid substances, which consists in that a sample of a substance containing metal ions and a thiol group or disulfide bonds is first subjected to analysis in the native state, i.e. not irradiated with UV radiation, irradiation, thereby generating spectral changes that are characteristic of the substance and changing the spectral characteristics of the sample before irradiation, or information contained in the non-irradiated sample data bank, and after irradiation with UV radiation, the characteristics of the substances are considered. |
