Laser-induced breakdown spectroscopy (LIBS) spectra interpretation and characterization using parallel factor analysis (PARAFAC): a new procedure for data and spectral interference processing fostering the waste electrical and electronic equipment (WEEE) recycling process

Abstract

For the first time, PARAFAC was used to interpret and characterize LIBS spectra, providing the pure spectra, the signal profile and relative concentration of base and noble elements present on a printed circuit board from the hard disk.
