Progress in Research and Application of Micro-Laser-Induced Breakdown Spectroscopy

Publication date: October 2018Source: Chinese Journal of Analytical Chemistry, Volume 46, Issue 10Author(s): Lan-Xiang SUN, Wei WANG, Xue-Yong TIAN, Peng ZHANG, Li-Feng QI, Li-Ming ZHENGAbstractThe technique of micro-laser-induced breakdown spectroscopy (μLIBS) usually refers to analyzing the surface of the sample using a compact focused laser beam in the optical microscope range. Compared to conventional laser-induced breakdown spectroscopy (LIBS), it can provide more abundant form, structure, and content information on a smaller, less sample condition. Hence, the application field is very wide. In this paper, the basic status of μLIBS in the selection of laser source and the structure of optical path system is introduced, and its application in metal, semiconductor, animal and plant fields is reviewed. The existing problems and potential development direction is pointed out.Graphical abstractThe technique of micro-laser-induced breakdown spectroscopy (LIBS) usually refers to analyzing the surface of the sample using a compact focused laser beam in the optical microscope range.
