Description

technical field [0001] The invention relates to the technical field of laser-induced breakdown spectroscopy, in particular to a laser-induced breakdown spectroscopy detection system. Background technique [0002] Laser Induced Breakdown Spectroscopy (LIBS) is an elemental composition analysis technique based on the emission spectrum generated by the interaction between laser and material. Laser-induced breakdown spectroscopy technology usually uses a laser-induced light source to generate laser light, ablate the sample to be tested to generate plasma, collect optical signals of the plasma through a spectrometer (or spectrophotometer, etc.), and then select the spectrum of a specific wavelength of the element to be analyzed The signal is processed to obtain qualitative and quantitative information of the sample components. During the measurement process, this technology is less destructive to the sample, and the sample consumption is extremely low. It has the advantages of ...
