We present here the new line installed at LMC14 for dissolved inorganic carbon (DIC) extraction from fresh and ocean water samples. The operating system and extraction process are described. The efficiency of the line design was checked, and the background (0.42 ± 0.11 pMC) and the reproducibility on artificial samples obtained by dissolution of IAEA-C1, IAEA-C2, and commercial bicarbonate in water were evaluated. Intercomparison with an independent lab (IDES) was also carried out on a natural sample. The line operates 3 samples a day under helium flow and is able to run samples up to 40,000 ka.
