Laser-induced breakdown spectrometer is a new analytical method in the field of spectral analysis. Its basic principle is to use a high-energy laser light source to form a high-intensity laser spot (plasma) on the surface of the analyzed material to excite the sample. Emit light, which is then analyzed by spectroscopic systems and detection systems. This technology is very sensitive to most inorganic elements in the material. It can also analyze low atomic number elements such as hydrogen and sodium, which are difficult to analyze using other techniques.
Spectrolaser is a cross-Sudan colleague sharing system and has been patented. Spectrolaser laser spectrometer has strong technical advantages:
·Can measure almost all natural elements, including H, Li, Be, C, N, O, S and other elements that are difficult to analyze by conventional methods;
·The sample preparation process is very simple, and the repeated pulse method can also be used to clean the sample surface or remove the surface coating;
·It only requires a small amount of sample (1-10g) Perform high-throughput analysis, greatly reducing analysis costs;
·Has ppm-level detection limit and high sensitivity, detection precision and accuracy;
·Non-destructive testing in the true sense, Only a trace amount of sample is consumed, and the laser incident on the sample will produce almost no heating effect;
·Elemental analysis can be performed on samples in any physical state, including solid, liquid, gaseous and various mixtures;

·Almost not affected by spectral interference;
·For all detectable elements, the analysis time can be reduced to about 20 seconds, which has obvious advantages over other analysis techniques;< /p>
·Good environmental adaptability, almost no special requirements. It only needs to be connected to the power supply to work, no water cooling or compressed air is required. Can meet the requirements of field experiments;
·Basically no periodic replacement of consumables, the laser can be used continuously for more than 600,000 times;
·Powerful analysis compatible with Windows operating system Software and spectral database.
