Development and validation of a measurement and calibration program for a LIBS Handheld Analyzer device for the qualitative and quantitative analysis of scrap samples (Id 275)

Laser-induced breakdown spectroscopy (LIBS) is a very effective tool for the inspection of scrap samples, allowing rapid in-situ analysis of the composition both in the laboratory and directly in the recycling process. LIBS can detect low atomic number elements (i.e. light elements), some of which, such as carbon, are critical for the accurate characterization of individual scrap. However, it is also possible to detect harmful elements such as fluorine or bromine and thus remove critical samples from the recycling process.
The LIBS technology is available as a handheld instrument and thus offers the possibility to perform cost-effective analyses in real time on site.
The use of a 'LIBS Handheld Analyzer' always requires the application of a device-specific measurement and calibration program.
The aim of the bachelor thesis is the development and validation of such a program for the qualitative and quantitative analysis of simple alloys, which can be used as a blueprint for the development of further analysis programs for more complex composite scrap.
