Abstract：Laser-induced breakdown spectroscopy has been widely applied in many fields as a promising technique for analysis and measure. Four kinds of incense (wormwood incense，Tibetan incense，sanders，agilawood) sample have been measured and analyzed by the method of libs and then we get the elements composition of the samples. The relative concentrations of Cu，Mn，Ca, Fe in these four kinds of incense are estimated by the method of statistical analysis. Based on local thermodynamic equilibrium assumption, the plasma temperature of Ca element is obtained. The experimental results will provide a basis for the feasibility of rapid detection and quantitative elemental analysis of incense with the laser-induced breakdown spectroscopy.
