我们进行了分析,以确定最合适的骨预处理协议,用于最近成立的放射性碳实验室在科隆大学,脑炎neAMS。在2组分析中,我们测定了取自3个14 C骨标准品(牛津猛犸、VIRI I和VIRI H)的子样本的14 C年龄,并补充了12个未知骨样本的年龄测定。我们的研究结果表明,强度和持续时间的酸和碱的步骤和糊化温度可能有一个更大的影响所获得的年龄比存在或不存在的超滤作为预处理步骤。
We conducted analyses to identify the most suitable bone pretreatment protocol to be used by the recently established Radiocarbon Laboratory at the University of Cologne, CologneAMS. In 2 sets of analyses, we determined 14C ages for subsamples taken from 3 14C bone standards (Oxford Mammoth, VIRI I, and VIRI H) complemented by age determinations of 12 unknown bone samples. Our results suggest that the strength and duration of the acid and alkali steps and the temperature of gelatinization might have a larger influence on the obtained ages than the presence or absence of ultrafiltration as a pretreatment step.
