A method for determining the platinum-group elements (PGEs) and rhenium (Re) in archaeological bronzes was developed. For 20 mg of sample, detection limits of 0.07 (Re) to 1.4 (palladium; Pd) ng g^–1 were achieved. The method was tested on standards and compared with measurements determined by the PGEs via matrix separation. The method was applied to 45 samples from the Bronze Age to the Middle Ages. In the process, the PGEs provided no further information for the Bronze Age samples. The samples from the Hallstatt and La Tène Period show increased contents of Pd and platinum (Pt). These contents distinguished the samples from all other samples and give an important indication of the possible ores used. Three groups can be distinguished in the Middle Ages by their Pd and Pt contents. One group falls into the field of Bronze Age samples. The other two groups have significantly higher Pd and Pt contents. One group has higher Pd than Pt contents, while the other group has exactly the opposite. In a sample, it is possible that the high contents of Pd and other PGEs indicate the use of copper shale in the Eisenach area.

考古青铜器中 PGE 和 Re 的测定：确定考古铜合金来源的新方法*

开发了一种测定考古青铜器中铂族元素 (PGE) 和铼 (Re) 的方法。对于 20 mg 样品，检测限为 0.07（Re）至 1.4（钯；Pd）ng g ^–1达到了。该方法在标准品上进行了测试，并与 PGE 通过基质分离确定的测量值进行了比较。该方法应用于从青铜时代到中世纪的 45 个样品。在此过程中，PGE 没有提供青铜时代样本的进一步信息。Hallstatt 和 La Tène 时期的样品显示 Pd 和铂 (Pt) 的含量增加。这些内容将样品与所有其他样品区分开来，并给出了可能使用的矿石的重要指示。在中世纪，可以通过 Pd 和 Pt 含量区分三组。一组属于青铜时代样本领域。其他两组的 Pd 和 Pt 含量明显较高。一组的 Pd 含量高于 Pt 含量，而另一组则正好相反。在一个样本中，
