Description

AMS, as an ultra-sensitive method, is increasingly used in the determination of 14C for studies on wide variety of fields. As a multi-nuclide 14C extended AMS system, TJUAMS has been operating at Tianjin University for seven years. The sample throughput of measured 14C has exceeded 6000. During the long-term 14C-AMS measurements and data processing, some new discoveries and ideas, such as the effect of strong or weak ion beam current on the experimental results, the suitability of using the machine δ13C value correction, and the problems faced in the measurement by small samples of graphite solid, are worth exploring and discussing. In this contribution, the relevant experimental tests, ideas and proposals will be presented in detail.
