LIBSyesLaser-Induced Breakdown SpectroscopyThe abbreviation of laser-induced breakdown spectroscopy is laser induced breakdown spectroscopy, which uses pulsed laser to focus 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 then be used for material identification, classification, qualitative and quantitative analysis.

lCan analyze multiple elements simultaneously, combining the advantages of traditional element analysis techniques in industrial sites

lDiversity of matrix morphology，Can detect almost all solid samples

1. Safe withoutXRadiation exposure does not require applying for a radiation instrument use permit from the Environmental Protection Bureau, nor does it require hiring a third-party environmental assessment company to issue radiation instrument environmental assessment reports on a regular basis every year; Users can operate with peace of mind, without worrying about irreversible damage to their bodies caused by radiation accumulation.

2. Quickly identify alloy grades, aluminum alloys only require1-2Seconds;

3. One click design, very easy to operate, no need for professionals to operate;

4. Can quickly measureC,H,Li,Be,BWaiting for light elements, users can choose appropriate analysis curves and configurations according to their needs;

5. High definition camera, combined with laser beam, can accurately analyze micro areas;
