摘要：

Since the establishment of the first radiocarbon accelerator mass spectrometry facility in Latin America in 2009, the Radiocarbon Laboratory team of Universidade Federal Fluminense (LAC-UFF) has worked to improve sample preparation protocols and increase the range of environmental matrices to be analyzed. We now present the preliminary results for DIC sample preparation protocols. The first validation tests include background evaluation with pMC value (0.35 +/- 0.04) using bicarbonate dissolved in water. We also analyzed surface seawater resulting in pMC value (101.38 +/- 0.38) and a groundwater previously dated from LEMA AMS-Laboratory with pMC value (12.30 +/- 0.15).
