Parchment from different sources has been analyzed by laser-induced breakdown spectroscopy (LIBS) for determination of Ca, Na, K, Mg, Fe, Cu, and Mn. The LIBS results were compared with results from inductively coupled plasma spectroscopy (ICP) and good correlation was obtained. Rapid distinction between modern and historical samples was achieved by discriminant analysis of the LIBS data. Animal type recognition was also possible on the basis of Mg/Cu emission peak ratio and Mg depth profiling.
已通过激光诱导击穿光谱法(LIBS)对来自不同来源的羊皮纸进行分析,以测定钙、钠、钾、镁、铁、铜和锰。将LIBS结果与电感耦合等离子体光谱法(ICP)的结果进行比较,获得了良好的相关性。通过对LIBS数据进行判别分析,实现了现代样本与历史样本之间的快速区分。基于镁/铜发射峰比率和镁深度剖析,也能够识别动物类型。
