The accurate measurement of the maximum possible number of elements in ancient ceramic samples is the main requirement in provenance studies. For this reason neutron activation analysis (NAA) and X-ray fluorescence (XRF) have been successfully used for most of the studies. In this work the analytical performance of inductively coupled plasma-optical-emission spectrometry (ICP-OES) and inductively coupled plasma-mass spectrometry (ICP-MS) has been compared with that of XRF and NAA for the chemical characterization of archaeological pottery. Correlation coefficients between ICP techniques and XRF or NAA data were generally better than 0.90. The reproducibility of data calculated on a sample prepared and analysed independently ten times was approximately 5% for most of the elements. Results from the ICP techniques were finally evaluated for their capacity to identify the same compositional pottery groups as results from XRF and NAA analysis, by use of multivariate statistics.
准确测量古代陶瓷样品中元素的最大可能数量是产地研究的主要要求。因此，中子活化分析（NAA）和X射线荧光分析（XRF）已成功用于大多数研究。在这项工作中，将电感耦合等离子体发射光谱法（ICP-OES）和电感耦合等离子体质谱法（ICP-MS）的分析性能与XRF和NAA的分析性能进行了比较，以对考古陶器进行化学表征。ICP技术与XRF或NAA数据之间的相关系数通常优于0.90。对于大多数元素，在独立制备和分析十次的样品上计算的数据的重现性约为5%。最后，通过使用多元统计方法，评估了ICP技术识别与XRF和NAA分析结果相同组成陶器组的能力。
