FIELD: measurement equipment.
SUBSTANCE: invention relates to the field of legal expertise, namely to methods of verification of date of creation of written documents. The task of creation of the method of determination of time of application of hand-written inscriptions on documents is the basis for the invention using the chromatography and spectroscopy of combinational dispersion of samples of colorants at action of radiation with the wavelength 785 or 532 nanometres.
EFFECT: expansion of limited period of determination, and also decrease of probability of error due to simultaneous use of the combinational dispersion chromatography and spectroscopy.
