Keck-NSF Paleoenvironmental and Environmental Laboratory

The University of Kansas W.M. Keck – NSF Paleoenvironmental and Environmental Laboratory directed by Dr. Randy Stotler is housed in the Multi-Disciplinary Research Building. This laboratory has capabilities for the analyses of a broad range of inorganic and organic samples including carbonates, bulk organic matter (TOC), specific compounds, gases, and water and dissolved gases. All instrumentation is optimized to handle the smallest sample sizes at the highest precision. The laboratory houses two mass spectrometry systems based on ThermoFinnigan Mat 253 Isotope Ratio Mass Spectrometers. The first system is exclusively a continuous flow system consisting of a ThermoFinnigan TC/EA and a ThermoFinnigan GASBENCH II interfaced via a Conflo III and Costech Elemental Analyzer.

The second system operates in dual-inlet or continuous-flow mode and peripherals consists of a ThermoFinnigan KIEL III interfaced to the dual-inlet and ThermoFinnigan Trace GC ultra interfaced via a GC/C III. The laboratory currently houses mechanical micro-balances and a variety of liquid-handling (micro-volumes) systems are available. A NewWave MIR 10-30 CO2 laser system can be interfaced to either mass-spectrometer. The laboratory is under the direction of Dr. Randy Stotler and daily laboratory operations are overseen by full time laboratory manager, Mr. Bruce Barnett, and staffed by graduate and undergraduate research assistants.
