Abstract
A liquid-chromatography method has been developed for the separation of amino acids with the same specific activity in radiocarbon from bones impregnated with isotopically dead petroleum compounds found in the La Brea tar pits. This technique permits the application of radiocarbon dating to such bone assemblages.
摘要
已经开发出一种液相色谱法，用于分离来自拉布雷亚沥青坑中含有同位素惰性石油化合物的骨骼中具有相同放射性碳比活度的氨基酸。该技术允许将放射性碳测年应用于此类骨骼组合。
