激光诱导击穿光谱对四种香的快速检测

激光诱导击穿光谱技术(laser-induced breakdown spectroscopy)作为一种极具前景的分析和测量技术应用日益广泛。对四种香(艾草香、藏香、檀香、沉香)样品进行了激光等离子体光谱测量和分析, 得到了样品中元素的成分；并且对四种香样品中的Cu，Mn，Ca和Fe四种金属元素典型谱线的强度进行了统计分析和元素含量的对比。基于等离子体的局域热动力学的平衡模型, 计算了Ca元素的等离子体温度。实验结果为采用激光诱导击穿光谱对香品成分进行快速检测和分析的可行性提供了依据。

Rapid Determination of Four Kinds of Incense by Laser-Induced Breakdown Spectroscopy

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.
