SYSTEM AND METHOD OF INVESTIGATION BY LIBS AND IR-SPECTROSCOPY OF ABSORPTION Russian patent published in 2017 - IPC G01N21/35 G01J3/443 

FIELD: physics.

SUBSTANCE: specimen property (114) determining (102) system comprises a LIBS-detector (104, 106) and an infrared absorption detector (108, 110) for the sample investigation (114) to create spectral LIBS data and spectral infrared absorption data, respectively; and a data processor (112) provided for applying, at least, one chemometric forecasting model, each of which is constructed for communication, preferably a quantitative communication, between the signs of the combined spectral LIBS data and the absorption data with the separate specific sample property, the combined data set derived of, at least, parts of the LIBS data and the absorption data, to create a definition thereof, preferably a quantitative definition, of the specific property associated about with the said model.

EFFECT: quantitative definition of the substance properties in a complex image matrix.
