LIBS – Laser-Induced Breakdown Spectroscopy

This method presents a chemical analysis of random solids marked by a punctate excitation of the sample’s material by laser pulses. The laser’s energy causes evaporation of a little mass of the substance of the sample’s surface.

The temporary formed plasma is utilized for the spectroscopic analysis (emission spectroscopy).

With reference material the calibration is possible. The calibration forms the basis for a qualitative analysis. The low time investment for the samples’ preparation and the analysis itself can be regarded as advantages.

On account of the punctate excitation the method is preferred for small objects (from circa 0,2 mm). The test pieces are presented unchanged after the process.

(Samples: massive samples, external specimen size at least 2 mm, object size from circa 0,2 mm)
