Abstract: Graphite targeting is one of the key steps in the radiocarbon chronology measurement of accelerator mass spectrometer. However, the process of sample graphitization is complicated and difficult to use. in order to further improve the utilization of accelerator mass spectrometer, we have purchased the AGE3 multi-functional carbon-14 graphitization system produced by Ionplus AG, Switzerland. This device can not only burn the treated organic sample through the combustion unit of EA to obtain CO2, but also hydrolyze and oxidize carbonate samples or water samples by adding acids in the CHS2 unit. The CO2 obtained above is separated and purified into the AGE3 reactor. By adding iron powder catalyst in advance, the CO2 is reduced to graphite under the action of hydrogen, and then can be pressed into a graphite target for carbon 14 measurement. Compared with the Zn-Fe flame sealing method, the AGE3 graphitization system has the advantages of simple operation and high efficiency. This presentation will briefly describe the principles, applications and operation procedures of the AGE3 system, and discuss the feasibility of processing low-carbon samples.
