Laser induced breakdown spectroscopy system

LIBS (Laser Induced Breakdown Spectroscopy) is an atomic emission spectroscopy technique that uses pulsed lasers to generate plasma while ablating materials. Spectral and temporal analysis of the light generated by bright plasma can provide information on the elemental composition of the sample.
LIBS technology can be traced back to 1962, when experiments were conducted using a ruby pulse microwave maser. In the 1980s, Leon Radiemski, David Cremers, and others from the Los Alamos laboratory in the United States made this technology applicable in reality and proposed the term LIBS.
Depending on the different elements being analyzed, the detection limit of LIBS technology can reach the ppm to ppb level. Also, there is no need to prepare the tested sample in advance (such as polishing, decomposition, etc.), and LIBS technology can analyze multiple materials.
Avantes' new improved AvaLIBS system is a portable LIBS system based on a Big Sky Ultra CFR Nd: YAG laser (50 mJ). It includes a suitcase that can hold up to six spectrometers. The power supply of the laser is external and connected to the main unit inside the suitcase through a detachable cable. The laser head of the LIBS system is connected to the main unit inside the suitcase through a flexible umbilical cord (3 meters long). If laboratory conditions permit, it can operate in an open light path mode. As an option, the laser head of LIBS system can be connected to a sample chamber, which can improve the safety of operation. The host is semi installed in a suitcase, and the laser head and umbilical cord can be stored and transported in the suitcase.
