The LIBS technique is based on the process of ionization of matter produced by focused laser pulses. The spectrum of the light emitted during electron recombination is collected and studied for the analysis of the material The LIBS technique was introduced more than 20 years ago by the group of David Cremers at Los Alamos, USA. Since then, LIBS has been successfully applied to the detection of trace elements and in situ analysis in hostile environment. The technique has ppm to ppt detection limits, depending on the element analyzed.
Furthermore, the sample does not need to be prepared (by polishing, disssolution, etc), and solid, liquid and gas samples can be analyzed. LaserPoint has developed a compact, high efficiency focusing/collecting head that allows the focusing of high energy YAG lasers onto the sample under analysis.
The emitted light is then collected axially, and analyzed in a multiple, high resolution Avantes Fast Trigger Fiber Optic Spectrometer AvaSpec-2048FT.
