dc.description.abstractIn this study we presented a new cosmogenic in-situ C-14 extraction line at the ICER laboratory, which is similar to be published in Fülöp et al. [1]. These extraction system used the phase transformation of quartz to cristobalite on high temperature in order to quantitatively extract the carbon as CO2. The system consists of three independent components. 1: used for remove the atmospheric and meteoric C-14, 2: offline high-temperature (1650 °C) oven for extract and trapped the cosmogenic in-situ 14C from quartz, 3: CO2 gas purification and mass measurement line. After the extraction and cleaning, the purified CO2 samples are measured with compact 14C AMS system (Environ MICADAS) and the gas ion source interface. The extraction line allows for rapid sample throughput of about 6 samples per week. The sample masses ranging between 4 and 7 g of clean quartz. Our first tests were on the borehole CO2 blank gas and Cronus standards. The blank level of the whole line is very low. We get similar experiences and results as Fülöp et al. [1]. Purified quartz samples were sieved and used for analyse the fraction of 250 – 500 µm. The carbon yield from quartz samples are very good and we have the expected values. The research was supported by the European Union and the State of Hungary. co-financed by the European Regional Development Fund in the project of GINOP-2.3.4-15-2020-00007 “INTERACT”.
