碳酸盐的放射性碳测年在考古学和气候研究中越来越重要。与大多数样品一样，这些样品通常需要预处理以去除表面污染。以不同保存阶段的蜗牛和贝壳为原料，研究了不同的预处理工艺和预处理过程中对酸溶的敏感性。我们发现简单的酸处理可以得到可靠的结果，尤其适用于非常脆弱的样品。我们还比较了方解石的转化使用元素分析仪（EA）和传统的酸溶解技术。
Radiocarbon dating of carbonates is of increasing importance for archaeology and climate research. Like most samples, these usually require pretreatment to remove surface contamination. We studied several pretreatment techniques using snails and shells of different stages of preservation and sensitivity to dissolution during the acid step of the pretreatment. We find that simple acid treatment leads to reliable results, and is applicable especially to very fragile specimens. We also compare conversion of calcite using an elemental analyzer (EA) to the conventional acid dissolution technique.
