Sixty-eight alcoholic beverages ranging in alcoholic degree between 40 and 55 from different countries were analyzed for their 16 most abundant metal elements using inductively coupled plasma (ICP) spectroscopy. The results were analyzed statistically using two different types of analytical methods: canonical discriminant analysis and classification binary trees. The aim of this study was to investigate which of the metals analyzed constitute diagnostic parameters that establish authenticity of the traditional Cypriot spirit zivania. The two statistical methods revealed that Mg, Zn, and Cu are promising distinctive parameters capable of differentiating zivania from other spirits similar in alcoholic degree. It is believed that this differentiation in metals between the alcoholic beverages examined is related to the unique geological and climatic conditions existing on the island of Cyprus.
使用电感耦合等离子体（ICP）光谱法对来自不同国家、酒精度在40至55度之间的68种酒精饮料进行了分析，以测定其中16种含量最丰富的金属元素。使用两种不同类型的分析方法对结果进行了统计分析：典型判别分析和分类二叉树。本研究的目的是调查所分析的哪些金属构成了确定传统塞浦路斯烈酒齐瓦尼亚真伪的诊断参数。这两种统计方法表明，镁、锌和铜是有前景的独特参数，能够将齐瓦尼亚与酒精度相似的其他烈酒区分开来。据信，所检测酒精饮料之间的这种金属差异与塞浦路斯岛上独特的地质和气候条件有关。
