Abstract
A system for sorting reusable raw-material pieces, where the chemical composition of the raw-material pieces is analyzed by laser-induced breakdown spectroscopy (LIBS), where the raw-material pieces in a first step are subjected to a plurality of first laser pulses in order to remove surface coatings and/or contaminants from the raw-material pieces, and in a second step, one or more further laser pulses from the same laser are used to generate a plasma.
