用户须知
14C、10Be和26Al的AMS测定是高技术含量分析技术,仪器测试精度和本底与样品类型、化学前处理、仪器稳定性、数据处理等有较大关系。目前仪器给出的测试精度为各个核素所用标准的测试精度,非实际样品测试精度。因此,送样人员需提前将待测样品的关键信息(如含碳量)告知仪器工作人员。
本实验室仅开展自然低放射性样品的测量,对人为添加示踪剂的生物样品、涉核活动、核设施、铀矿等存在高放射性的样品不予测量。请送样人员提前告知样品来源并做承诺,如有不实或隐瞒不报的情况,本实验室有权追究其法律责任。本实验室主要用于基础科学研究,对涉及商业价值纠纷的样品不承担法律责任。
请用户在进入本实验室开展实验之前,务必阅读相关注意事项及文献,提前了解样品准备和技术方法等。
