Finnigan MAT 252

Finnigan MAT 252 isotope ratio mass spectrometer configured for H₂, CO₂, N₂, O₂, CO, and SO₂. In the current configuration, the MAT 252 is coupled to the “in situ” laser-florination extraction line and is used for δ¹⁸O and δ¹⁷O analyses of silicates, δ¹⁸O by CF-TCEA, and δ²H measurements using conventional offline techniques.
