LIBS在气溶胶诊断方面的应用
Application of LIBS in Diagnosis of Aerosol
摘要
激光诱导击穿光谱技术(laser-induced breakdown spectroscopy, LIBS)是一种原子发射光谱技术,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,对光谱进行分析即可 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 advantages, 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.
