Museum collections are extremely valuable sources of material for ongoing research, although the conservation history of some objects is not always recorded, which can be problematic for chemical analyses. While most contamination is removed using the acid-base-acid treatment, this may not be the case for cross-linked contamination. The XAD resin protocol was implemented at the radiocarbon (14C) laboratory in the Muséum national d’Histoire naturelle, and the setup was tested using known age bone samples and a consolidated Palaeolithic bone. Known age samples were consolidated with shellac or Paraloid, aged for a month, treated with or without the XAD resin and 14C dated. Bone blank results showed that XAD resin was able to remove shellac, which was not the case for the ABA-only method. Results from VIRI I were more variable and VIRI F was possibly too young to show the effects of the consolidants. Two 14C dates on the Palaeolithic bone after XAD treatment are statistically the same, while a sample without XAD treatment was significantly older, suggesting that the contaminant was not fully removed by the ABA-only treatment. This study demonstrates the potential of the XAD treatment to clean heritage bone samples stored in museums prior to geochemical analyses.

博物馆藏品对于正在进行的研究来说是极其有价值的材料来源，尽管某些物品的保存历史并不总是被记录下来，这对于化学分析来说可能是个问题。虽然大多数污染物可以通过酸-碱-酸处理去除，但对于交联污染物来说情况可能并非如此。XAD 树脂协议在国家自然历史博物馆的放射性碳 ( 14 C) 实验室实施，并使用已知年龄的骨骼样本和合并的旧石器时代骨骼对设置进行了测试。将已知年龄的样品与虫胶或Paraloid 合并，陈化一个月，用或不用XAD 树脂处理，并标有14 C 日期。骨空白结果表明，XAD 树脂能够去除虫胶，而仅使用 ABA 的方法则不然。VIRI I 的结果变化较大，而 VIRI F 可能还太年轻，无法显示固结剂的效果。XAD 处理后的旧石器时代骨骼上的两个14 C 年代在统计上是相同的，而未经 XAD 处理的样本则明显更老，这表明仅使用 ABA 处理并未完全去除污染物。这项研究证明了 XAD 处理在地球化学分析之前清洁博物馆中存储的遗产骨骼样本的潜力。
