The Organic Geochemistry Laboratory in the University of Arizona Department of Geosciences is designed for environmental and paleoclimatic applications. We are not a service lab, but if you are interested in pursuing analyses please get in touch. Here are some details about our equipment.
"Bowie"
A Thermo Scientific Delta V Plus stable isotope mass spectrometer with a Conflo IV, Trace 1310 GC, and GC Isolink II. Designed to measure stable carbon and hydrogen isotopes on individual organic compounds. We mostly measure leaf wax compounds, which we use to reconstruct past changes in vegetation and hydroclimate.
"Saguaro"
An Agilent 6210 single quadrupole mass spectrometer with a 1260/1290 Infinity high-performance liquid chromatograph. We use this to measure GDGT compounds, which tell us about past temperatures.
"Ocotillo"
An Agilent 5977 single quadrupole mass spectrometer with a 7890 gas chromatograph. We use this for ID’ing unknown molecules in our samples.
"Palo Verde"
A stand-alone Thermo Scientific Trace 1310 GC with a flame ionization detector. A workhorse of the lab, we use this for compound screening and quantification.
"Cholla"
A stand-alone Agilent 7890 GC with a flame ionization detector and one more trick up its sleeve: a modulator for GC X GC analyses.
