古陶瓷的痕量元素分析已被证明是追踪这种材料的循环的非常有用的工具。仪器中子活化分析(INAA)多年来一直是测量陶瓷成分的首选分析技术，因为它可以测定大量的元素和良好的灵敏度。最近，一些文献表明，激光烧蚀-电感耦合等离子体质谱(LA-ICP-MS)可以更快、更低的成本获得与中子活化分析类似的结果。建立了用LA-ICPMS测定51种元素的方法，并对以前用INAA分析的瓦里期陶瓷进行了测试。我们展示了INAA和LA-ICPMS分析如何在样本分组方面得出相同的结论。
Trace elemental analysis of ancient ceramics has been proven a very useful tool for tracing the circulation of this material. Instrumental neutron activation analysis (INAA) was for years the analytical technique of choice to measure the composition of ceramics because of the large number of elements it could determine and its good sensitivity. Lately, a few publications have shown that laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) could provide similar results as INAA more quickly and at lower cost. A protocol has been developed to determine 51 elements using LA-ICP-MS and tested it on Wari period ceramics previously analyzed using INAA. We show how INAA and LA-ICP-MS analysis lead to the same conclusion in terms of sample groupings.
