摘要/Abstract

摘要：

LIBS是一种原子发射光谱技术，其基本原理是利用强脉冲激光把待测样品表面烧蚀、激发为等离子体，然后用光谱仪和CCD记录等离子体发射的光谱，对光谱分析即可得到待测物质中元素的种类和浓度信息。LIBS技术由于具有快速、无需对样品预处理、可同时测量多种元素以及适应固体、液体和气体等多种样品形态的优点，被称为未来化学分析之星，它在实现气溶胶原位检测上具有极大的应用潜力。

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
