Abstract:

Laser-induced breakdown spectroscopy (LIBS) is an atomic emission spectrum technique. Its basic principle is to use strong pulsed laser to ablate and excite the surface of sample to be plasma, then the plasma emission spectrum can be recorded by spectrometer and CCD. The information of composition and concentrations of elements in the material can be obtained through the spectrum analysis. LIBS technology is referred to as the future star of chemical analysis because of its advantaes, such as fast detection, no need of sample pretreatment, simultaneous measurement of various elements, and adaptability to various sample state including solid, liquid and gas. It has great application potential on the realization of in-situ detection of aerosols.

Key words: laser-induced breakdown spectroscopy, serosol, spectroscopy diagnosis
