Upgraded in 2016, Thermo Delta V plus IRMS; the mass spectrometer is equipped with universal triple collectors and three additional Faraday cups for multiple sulfur isotope analyses by the SO-SO2 method in continuous flow. The Delta V is linked to the two elemental analyzer peripherals with a Conflo IV, two NC 2100 and ECS 4010 elemental analyzers to generate SO2 gas for multiple S isotope analysis and CO2 and N2 gases for C and N isotope analyses, respectively.
