In this paper we present the system we have developed in Lecce for the sample preparation of organic and inorganic materials for accelerator mass spectrometry measurements. The system consisting of two separated lines for CO2 transfer and graphitization will be described. It includes an equipment we specifically realized for cracking the tubes containing the CO2 gas produced from the sample. The performances of the whole system and the memory effects have been investigated by using test samples like oxalic acid II as modern sample, and IAEA C4 standard as blanks. The study of the reduction process versus time and temperature and a spectroscopic investigation of the graphite is also given.
