| The University of Chicago has a long
tradition of making stable isotope analysis to help us
understand nature, the world, and the entire universe
around us. Harold
Urey, Harmon
Craig, Jacob
Bigeleisen and
Marie Goeppert Meyer, amongst others, were at
The University of Chicago (see
page 10, "Reference Materials in Isotope
Geochemistry.") We carry on those
traditions, doing conventional isotopic analysis to
follow packets of water in the ocean, to understand
modern food webs and ecosystem dynamics, and to put
together constructs of paleo environments. Newer
methods have been implemented and used in projects
looking at paleo-elevation which has roles in plate
techtonics and atmospheric circulation. "call me Al" |
What we analyse 13C and 15N in organic samples (bulk) 18O and D/H in water 13C in dissolved inorganic carbon (DIC) 13C and 18O in carbonates Clumped isotopes in CO2 |
| What we do: for facility users - training - starting supplies - standards - method development - help with samples - quality control We also can do service work on samples, including limited sample preparation. |

Albert Colman's stable isotope
ratio mass spectrometers were setup in 2010 (thanks
Burt and Ian from Thermo, Brian and the rest of the U
of C gang for getting the renovations done, and U of C
and the NSF forfunding), and real samples were being
run in early 2011. Albert Colman has since moved to
Rice, but the instruments are still here. This is mainly set up to be a facility for use by the University of Chicago community, but is available for other users and limited service runs. Acknowledgements: The purchases of the major pieces of equipment, mass spectrometers and peripherals, were supported by NSF award #0923831. "This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)." And many thanks to the U of C for the needed renovations and added support for the laboratory.
