W. M. Keck Paleoenvironmental and Environmental Stable Isotope Laboratory


The University of Kansas W.M. Keck – NSF Paleoenvironmental and Environmental Stable Isotope Laboratory (Dr. Marina Suarez, Director) is located in EEEC’s Slawson Hall.  The laboratory houses two isotope ratio mass spectrometers and provides analyses of stable isotopes (H, C, N, O) from liquids, solids and gases.

Clients wishing to submit samples for analyses should contact kpesil-geo@ku.edu or lab director (mb.suarez@ku.edu). A price list is available (see below) for our most routinely analyzed materials/isotopes, but we can accommodate special requests.

Instrumentation and routine analyses include:

  • Thermo Kiel IV Carbonate device connected to Thermofinnigan MAT 253 for the analysis of C and O stable isotopes in carbonates
  • Costech 4010 Elemental Analyzer connected to Thermofinnigan MAT 253 for the analysis of C and N stable isotopes in organic materials
  • Gasbench II connected to Thermofinnigan MAT 253 for the analysis of H and O stable isotopes in waters, C isotopes in gasses and dissolved inorganic carbon,  and C and O isotopes in carbonates
  • Thermofinnigan TC/EA for the analysis of O and H stable isotopes in solids (specifically phosphates) and liquids.
  • ThermoFinnigan Trace GC ultra-GC/C III for the analysis of C and H stable isotopes in methane
