Conventional separation usually applied to segregate homogeneous fractions from mixed scrap often require a multi-step sorting with very different sensor based classification techniques. While most of these methods have very limited measurement capabilities for particular types of scrap only, laser-induced breakdown spectroscopy (LIBS) provides a precise characterization for a wide range of scrap metals at the same time based on chemical multi-elemental analysis of the atomic composition. Short pulse laser radiation generates a plasma of excited atoms and ions that – when recombining – emits a characteristic line spectrum of all chemical elements present similar to a fingerprint. Thus, a variety of recyclable materials like metals and alloys can be analyzed qualitatively and quantitatively.

The LIBSorter 300 is a versatile inline analyzer for the online classification of scrap metals in industrial recycling. The chemical multi-elemental analysis of scrap by means of laser-induced breakdown spectroscopy provides the reliable classification of customized and homogeneous fractions for subsequent separation. The LIBSorter 300 gains advantage over the commonly used multi-step recycling by classifying extensive high-quality secondary raw materials within a single process step only.
