This laboratory has the capability to analyse total mercury (Hg) in any kind of solid and liquid samples (e.g. water, sediment, soil, particulate material, biological material, food, etc). This service includes two equipments: the AMA-254 from Leco and a brand-new DMA-80 EVO double beam from Milestone. In both devices, the procedure is based on the thermal decomposition of the solid sample, gold trap amalgamation, thermal desorption and detection by atomic absorption spectrophotometry using the method EPA 7473, as well as the ASTM D-6722-01 and the ASTM D-7623-10 methods.
