LAC-UFF

The Radiocarbon Laboratory of the Fluminense Federal University (LAC-UFF) was created in 2009 aiming to make the Accelerator Mass Spectrometry (AMS) technique accessible for Brazilian researchers. High quality studies developed by national research groups in areas such as Archaeology and Geosciences resulted in a large number of samples being sent for 14C analyses abroad, evidencing the need for a 14C laboratory to serve the Brazilian scientific community. Until then, the Center of Nuclear Energy in Agriculture of the University of São Paulo (CENA-USP) was the only active Brazilian radiocarbon laboratory, offering analyses by the conventional technique.

In 2009, the LAC-UFF already had all the necessary infrastructure for the preparation of samples of different materials for AMS measurements, including a vacuum system for purification and graphitization, developed in the laboratory itself. After a series of tests and inter-comparisons with laboratories in the USA and with the CENA-USP, the LAC-UFF obtained satisfactory results and became part of the list of laboratories recognized by the international radiocarbon community, available at www.radiocarbon.org. Four decades after the development of the AMS technique and subsequent proliferation of laboratories around the world, in 2012 the installation of a Single Stage Accelerator Mass Spectrometry (SSAMS) system completed the infrastructure of the first 14C-AMS laboratory in Latin America and, until the present, the only one of South America.

The creation of the LAC-UFF made the 14C-AMS technique available to national groups with costs much lower than those required to prepare and measure samples abroad. This reduction of costs allowed the accomplishment of a large number of studies in interdisciplinary areas, motivating the creation of an extensive network of national and international collaborators. Currently the laboratory offers scientific collaborations and commercial services.

The Radiocarbon Laboratory of the Fluminense Federal University was installed in 2009 as a sample preparation lab.

In 2012 a 250 kV Single Stage Accelerator System was installed, LAC-UFF becoming the first 14C-AMS facility in Latin America.

After 10 years of scientific research more than 30 students have learned to work with 14C-AMS at LAC-UFF.
