METHOD FOR IDENTIFYING THE TRUTH OF PHARNACEUTICAL TABLET USING ATTENUATED TOTAL REFLECTANCE-FOURIER TRANSFORM INFRARED SPECTRUM

摘要

The present invention relates to a method for identifying the truth of pharmaceutical tablet using attenuated total reflectance Fourier transform infrared spectrum. The invention comprises: (1) a stage of obtaining subject spectrum on the coating film of the subject tablet; (2) a stage of obtaining the characteristic value of the subject spectrum from the subject spectrum and selecting it using the search key of the subject tablet; (3) a stage of selecting the characteristic value of the genuine spectrum corresponding to the characteristic value of the characteristic value of the subject spectrum from the database of the attenuated total reflectance Fourier transform infrared spectrum in order to use it as the search key of the genuine tablet and searching whether the search key of the genuine tablet is equal to the search key of the subject tablet; and (4) a stage of outputting the information whether the search key of the subject tablet and the search key of the genuine tablet meet the equality requirement.
