摘要

考古发现的化学特征描述需要持续关注纳米/微创方法的发展。通过这些方法可以深入了解物品的历史背景、生产工艺和保存状况,往往能揭示出数百年来意外保存下来的材料的惊人特性。这项工作旨在描述 20 世纪 80 年代在吉利奥岛附近的坎佩塞湾进行考古发掘时发现的一种假定的历史树脂的分子组成特征。这种树脂是从用于葡萄酒运输的贸易双耳瓶中提取的样本;它很可能被用作一种涂层,以确保容器具有更好的防水性。我们采用 GC-MS 直接进样法检测了特定的分子标记。此外,我们还通过固相微萃取(SPME)和气相色谱-质谱联用技术研究了同一样品的挥发性成分,以满足对快速、无溶剂和现场兼容的样品制备方法的需求。

The scent of an archaic wreck: minimally invasive characterisation of archaeological finds

The scent of an archaic wreck: minimally invasive characterisation of archaeological finds

The chemical characterisation of archaeological finds necessitates a continuous focus on the development of nano/micro-invasive methodologies. These methodologies yield insights into the historical background, production processes, and conservation state of the items, often revealing astonishing properties of materials that have been unexpectedly preserved over the centuries. This work aims to characterise the molecular composition of a putative historical resin recovered during an archaeological excavation in Campese Bay off the island of Giglio in the 1980s. The resin was sampled from a trade amphora used for wine transport; it was likely employed as a coating to ensure better waterproofing of the containers. The characterisation was performed by detecting specific molecular markers using a GC–MS direct injection approach. In addition, we investigated the volatile fraction of the same sample through solid-phase microextraction (SPME) coupled with GC–MS to address the need for a fast, solvent-free, and field-compatible sample preparation method.
