AMS graphitization system in the Dendrochronological Laboratory at AGH-UST, Kraków: a) Reduction line and vacuum line for sample sealing and purification of CO2; b) cryogenically separation CO2 from water in glass vessel cooled in a dry ice/ethanol slurry and trapping CO2 in the glass valve cooled by liquid nitrogen; c) shows the vacuum line for graphite preparation.

Changes in CO2 pressure during reduction for some of the reduced samples.

The results of 14C AMS measurements of the samples prepared using the graphitization line in the Dendrochronological Laboratory at AGH-UST Krakow.
