摘要
We develop a system to measure the elemental composition of unprepared samples using laser-induced breakdown spec-troscopy (LIBS) in our laboratory,which can be used for the determination of elements in solids,liquids and aerosols. A description of the instrumentation,including laser,sample chamber and detection,is followed by a brief discussion. The time-resolved LIBS of aluminum at atmospheric pressure is presented. At the end,the possibilities and later uses of this technique are briefly discussed.
