The current development of laser-induced plasma spectral analysis technique

In the present paper, the productions by applying laser-induced plasma spectral analysis technique in different research fields were summarized. Many examples of the application based on laser-induced breakdown spectroscopy (LIBS) and laser-induced plasma spectroscopy (LIPS) methods were introduced, including the substance composition and correlative characteristics of the solid samples (e. g. metal alloy, soil, concrete, mineral, fossil, medicine etc.), liquid samples (e. g. solution, pure water, liquid jets etc. and gaseous samples (e. g. air, pure gas, vapor and aerosol etc.). Some other investigations and applications were also included. The factors which influence the detection capability, were discussed. Laser wavelength, pulse energy, power density, environmental atmosphere, external electric field, carbon layer on sample surface, sample material characteristic, and, so on all have effects on the precision and the limit of detection. Finally, a simple introduction of the improvements in experimental equipment and methods was also covered. The development of laser-induced plasma spectral analysis technique creates favorable conditions, such as convenience and shortcut, for many science and application researches. It plays an important role in the grogress in science and technology.
