Originální abstrakt

There are two main complications when analysing a sandstone-hosted uranium ore by means of LIBS, first one is the matrix effect which causes significant signal changes with respect to the complicated ore composition. The second one is the detection of uranium itself, which is made difficult by the fact that the number of uranium lines exceeds 5000 in the range from 384.8 to 908.4 nm. This work shows unconventional approach to LIBS spectra analysis. First step consists of creating a “master” spectrum, which should contain all possible elemental emission lines in the dataset. Second step is line by line identification and principal component analysis (PCA) of detected LIBS/LIP spectra.
