The Alabama Stable Isotope Laboratory is equipped with two isotope ratio mass spectrometers. Pictured above is a Thermo Delta V set up to receive sample gas via continuous flow. Peripherals of the Delta V include: Costech EA, Thermo Gasbench II, Thermo TC/EA. The EA and TC/EA are interfaced with a Conflo IV. The second IRMS, a Thermo Delta Plus, is pictured below and can accept sample gas through its dual inlet or by continuous flow (Gasbench II).
