在本文中，我们比较了六种不同的多元素沉积物分析考古目的。从考古发掘在德国和土耳其的代表功能，混合碎片和场外样品的两组不同的样品提取与硝酸，盐酸，王水（AR），DTPA和NH 4 NO3，并使用ICP-OES技术测量。将结果彼此进行比较，并与通过便携式X射线荧光光谱仪（pXRF）获得的总元素含量进行比较。DTPA和NH 4 NO3提取被认为不适合考古背景下的多元素分析，因为它们与所有其他方法的相关性较差。NH 4 NO3显示的数值不能反映已知的沉降活动。AR、HNO 3、HCL和pXRF结果确实反映了沉降历史，并且高度相关。通过使用多元统计（PCA），所有这些方法都实现了不同样本类别（特征、混合碎片和场外）的分离。pXRF是一种廉价且快速的方法，可以在挖掘现场轻松执行，从而可以消除繁琐的样品运输。我们提供的证据表明，pXRF是非常适合在考古背景下的多元素分析。
In this paper we compare six different multi-element sediment analyses for archaeological purposes. Two different sets of samples from archaeological excavations in Germany and Turkey representing feature, mixed-debris and offsite samples are extracted with HNO3, HCl, Aqua Regia (AR), DTPA and NH4NO3, and measured using ICP-OES techniques. The results are compared to each other and the total elemental content obtained by a portable X-ray fluorescence spectrometer (pXRF). DTPA and NH4NO3extraction were found not to be suitable for multi-element analysis in the archaeological context, as they displayed poor correlations with all other methods. NH4NO3showed values not reflecting the known settlement activities. AR, HNO3, HCL and pXRF results do reflect the settlement history and are highly correlated. A separation into different sample categories (feature, mixed-debris and offsite) was achieved for all those methods by using multivariate statistics (PCA). pXRF is a cheap and quick procedure which can be easily performed at an excavation site and can thus eliminate cumbersome sample transport. We provide evidence that pXRF is highly suitable for multi-element analysis in the archaeological context.
