Thermo-Finnigan MAT 253 Mass Spectrometer

MAT 253 Mass Spectrometer

This instrument is equipped with a "gas bench" for isotopic analyses of water and carbonates, the latter following acid dissolution, and a Thermally-Coupled Elemental Analyzer (TC-EA - essentially a furnace) for use with solid or organic samples to study O, N, C, and S isotopes.

Dr. Perry is using the MAT 253 to study the isotopic signature of hurricane precipitation.

Dr. Loubere and his students use the MAT 253 and its automated acid reaction system to analyze the stable isotopes of marine calcite microfossils.

Dr. Lenczewski is using the TC-EA apparatus to examine the isotopic composition of elements along a core taken from a tree.
