UASIL is housed in the new Biology Research Laboratory Building (Ferritor Hall). We have three isotope ratio mass spectrometers (one Delta XP and two Delta Plus IRMS systems) for stable isotope analysis allowing the capability to measure the C, N, O, or H isotope composition of trace gasses, solid, and liquid samples. To compliment our compound-specific IRMS (Isotope Ratio Mass Spectrometry) work, we have an Agilent GC with a Quadrupole mass spectrometer for compound identification and quantification.
