Laboratory/Desktop LIBS Spectrometer

LIBS laser-induced breakdown spectroscopy system

The LIBS (Laser Induced Breakdown Spectroscopy) laser-induced breakdown spectroscopy system focuses ultra short pulse laser on the surface of a sample to form a plasma. The emission spectrum of the plasma is analyzed using a spectrometer to identify the elemental composition of the sample, which can be used for material identification, classification, qualitative and quantitative analysis.

TrLIBS-LABlaboratoryThe LIBS laser-induced breakdown spectroscopy system mainly consists of a laser, high-resolution spectrometer, LIBS optical path collection probe, XYZ sample chamber, trigger delay controller, etc. Due to its modular design and strong scalability, it is very suitable for scientific research, LIBS optical application experiments, optical application centers and other users. Different lasers and spectrometers can be flexibly configured according to specific needs.

Main application areas

lCoal quality analysis and combustion product analysis

lOnline component analysis in the metallurgical industry

lMineral exploration and online analysis of ore quality

lSoil heavy metal analysis, biomaterials, aerosols, nanoparticles

lNuclear materials, waste, petroleum products

lBuilding materials, archaeology, casting, gold and jewelry testing

The detection limit of LIBS largely depends on the type of sample being tested, the type of element, and the specific selection and configuration of the laser and spectrometer. Based on the above reasons, the detection limit of LIBS can range from a few ppm to the% level. In most conventional applications, the LIBS detection limit can reach 10 ppm to 100 ppm for the vast majority of elements. In quantitative analysis, the relative standard deviation of measurement results obtained through LIBS can reach within 3-5%, while for homogeneous materials, it can usually be within 2% or even<1%.

The usual detection limit of LIBS

lElements such as Li, Be, B, Na, Mg, Al, K, Ca, etc.>10ppm, which is 0.001%

lTi, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Mo 等元素>100ppm即0.01%

lC. Elements such as N, O, P, Si, etc.>200ppm, which is 0.02%

lF. Cl, Br, S and other elements>0.5%
