LIBS is a type of atomic emission spectroscopy for the qualitative and quantitative chemical multi-elemental analysis in real time for a wide range of applications. Quantitative analysis is based on calibration with reference materials containing different analyte concentrations. Depending on the analyte-matrix, element concentrations in the low ppm-range can be measured.

• Perform the calibration and quantification of solid samples; • Create different programming scripts for specific types of analysis (knowledge of Python language is required).
