ABSTRACT The aim of this paper is to present the results of XRF analysis of archeological samples in two different states of preservation: intact vessel surfaces and transformed into powder. To investigate the effect of sample processing for XRF analysis, a handheld spectrometer was used. In total, 41 pottery samples were measured. The samples were extracted from Late Bronze Age and Early Iron Age ceramic vessels of two different technological traditions: local (hand-made pottery) and exogenous (wheel-thrown pottery) from the archeological site of Setefilla (western Andalusia, Spain). Multiple statistical tests were used to examine the effect of sample processing on the semi-quantitative outcome of XRF analysis of pottery. The results obtained from intact samples are considerably different from the results obtained from pulverized samples. The analyses revealed that levels of Co, Sb, Sn, Al, Si, Ca, Fe, S, K, Sr and Nb were higher in the group of intact samples. This study underlines the need to evaluate sample preparation when designing archeometric research programs.

样品处理对考古陶器 XRF 结果的影响

摘要 本文的目的是展示考古样品在两种不同保存状态下的 XRF 分析结果：完整的容器表面和转化为粉末。为了研究样品处理对 XRF 分析的影响，使用了手持式光谱仪。总共测量了 41 个陶器样品。样品是从青铜时代晚期和铁器时代早期陶瓷器皿中提取的，这些陶瓷器具有两种不同的技术传统：本地（手工制作的陶器）和来自 Setefilla（西班牙安达卢西亚西部）考古遗址的外源性（轮抛陶器）。多项统计测试用于检查样品处理对陶器 XRF 分析半定量结果的影响。从完整样品获得的结果与从粉碎样品获得的结果有很大不同。分析表明，完整样品组中 Co、Sb、Sn、Al、Si、Ca、Fe、S、K、Sr 和 Nb 的含量较高。这项研究强调了在设计考古研究计划时评估样品制备的必要性。
