Method for quality control of alternative medicines (generic and similar) scattered X-rays

摘要

"The method of quality control of alternative medicines (generic and similar) scattered X rays.The present invention consists in the classification of complex organic matrices using conventional equipment EDXRF (English, energy dispersive X - ray fluorescence).With the spreading of X-ray beam that appear in the spectra obtained with a chemometric tool known as principal components analysis (PCA,The English main component analysis), which is a fundamental logical mathematical tool.This new method of analysis and classification can be implemented, mainly in the pharmaceutical industries or industries which produce these types of drugs.Manufacturers or consumers of raw material of this type, in addition to sectors that assess the integrity of consumer goods (solid.Semi - solid or liquid) to import and export may be potential users of this new technique.More specifically, the present invention applies PCA as a mathematical model of the program used.Obtaining data that allow the visualization of the different classes for different types of drugs, due to the different composition of the matrices of these samples.Thus, the new analytical method, the object of this invention presents advantages for its simplicity and speed, with low cost of analysis.Optimized and used for the classification of various types of products.It is worth mentioning, this invention can be applied in many other samples solid, semisolid and liquid such as: fruit for classification of varieties, food in general, paints,Folders, plants and polymers.
