Amino Acid Geochronology Lab

PI:  Gifford Miller

Equipment:
  2 Agilent HPLCs (one with a diode array detector)

Description:  The Amino Acid Geochronology lab is setup to primarily date carbonate samples (e.g., mollusk shells, bird eggs). This can be done in either an ion-exchange configuration or in a reverse-phase configuration depending on sample type and data requirements. Additionally, with the use of a diode array detector we are equipped to measure pigments in lacustrine sediments.

For more information about our lab, or to submit samples for analysis, please contact Steve DeVogel

Earth Systems Stable Isotope Lab (Coming soon! Expected completion Spring 2016)

PI:  Katie Snell

Equipment:  2 magnetic sector, gas-source stable isotope ratio mass spectrometers and associated peripherals and preparation facilities.

Description:  This facility will house 2 magnetic sector, gas-source stable isotope ratio mass spectrometers and associated peripherals, with dual-inlet and continuous flow configurations. One instrument will be used to measure low abundance, multiply-substituted isotopologues of CO2 and other molecules for high precision applications such as carbonate clumped isotope thermometry. The second instrument will be capable of C,H,N,O and S continuous flow stable isotope analysis of solids and gases by headspace sampling, online combustion and high temperature conversion elemental analysis, with applications in a broad range of disciplines including geology, ecology, anthropology, microbiology and forensics. In addition, the facility will house equipment for sample processing including solid sample preparation, and custom-made, on-line and off-line vacuum extraction systems.

We intend to make this lab available to in-house and outside users. Please contact Katie Snell directly with questions about details or planned capabilities of the lab.

Electron Microprobe Facility

PI:  Kevin Mahan / Julien Allaz

Equipment:  JEOL JXA-8600

Description:  An electron microprobe is an electron microscope designed for the non-destructive x-ray microanalysis and imaging of solid materials. It is capable of high spatial resolution (1 µm beam size) and relatively high analytical sensitivity. The analytical facilities' JEOL JXA-8600 can acquire digital secondary-electron and backscattered-electron images as well as elemental x-ray maps. It is equipped with 4 wavelength-dispersive spectrometers and an energy-dispersive spectrometer.
Our microprobe is nominally capable of analyzing a wide range of elements (from Be through U), at concentrations typically above 100 parts per million. This instrument has very good electronic and analytical stability, vacuum cleanliness, and capability to perform analyses with high precision and accuracy as demonstrated by a history of applications.

Our facility is available to in-house and outside users. For rate, scheduling and other information, please visit the website or contact Julien directly.

Organic and Isotope Geochemistry Laboratory

PI:  Julio Sepúlveda and Sebastian Kopf

Equipment:  Hewlett Packard 6890 Gas chromatograph with Flame Ionization Detector · ThermoQuest Trace GC coupled to a Thermo Polaris-Q ion-trap mass spectrometer · Gas chromatograph-triple quadrupole-mass spectrometer (GC-QQQ-MS; coming soon) · Liquid chromatograph-quadrupole-time of flight- mass spectrometer (HPLC-QTOF-MS; coming soon) · Gas chromatograph-combustion-isotope ratio-mass spectrometer (GC-c-ir-MS; coming soon)

Description:  The Organic and Isotope Geochemistry Laboratory focuses on the extraction, purification, separation, and chemical and isotopic characterization of organic molecules extracted from a wide array of environmental (e.g., water bodies, sediments, soils, microbial systems) and culture samples, and their fossilized remains preserved in the rock record. Our research group studies the interplay between microbial and biogeochemical processes, and climate in contemporary environments, and paleo-ecosystems across Earth history. The laboratory serves as an analytical platform for research fields such as biogeochemistry, geobiology, astrobiology, environmental microbiology, energy, archaeology, and paleoceanography and paleoclimatology, among others.

***NEW Lab coming soon! Expected completion Spring 2016 Our new state-of-the-art analytical facility will be located in new Sustainability, Energy and Environment Complex (SEEC).

Raman Microspectroscopy Lab

PI:  Alexis Templeton

Equipment/Description:  The Raman Microspectroscopy Lab is equipped with a Horiba LabRAM HR Evolution Raman microscope-spectrometer capable of fast, non-destructive chemical imaging of a diversity of material types, including minerals (thin sections & powders), biological samples, fluids, dissolved gases, and much more. The instrument is equipped with two lasers (532 nm and 785 nm), motorized stage controllers, numerous microscope objectives (10-100x), and two diffraction gratings in order to vary the spectral window and spectral resolution. The microscope is fully confocal, allowing 3-D Raman imaging with up to 1 µm spatial resolution in all three dimensions. We are further equipped for time-lapse Raman imaging and polarization Raman analysis.

Our facility is available to in-house and outside users. For additional information regarding our lab, rates, and scheduling, please contact the Raman Lab manager Eric Ellison or PI Alexis Templeton.

Thermal Ionization Mass Spectrometry Facility
   and Clean Room


PI:  G. Lang Farmer

Equipment:  6-Collector Thermal Ionization Mass Spectrometer

Description:
  The Benson Earth Sciences Building houses an ~1,300 sq ft. clean chemistry laboratory and 6-collector thermal ionization mass spectrometer for high precision Nd, Sr and Pb isotopic measurements from natural materials, including rocks, soils and groundwaters. The facility includes a New Wave Micromilling device for in situ microsampling of thin and thick rock sections, two laminar flow fume hoods certified for the use of perchloric acid, and an ultramicrobalance. Lab personnel are also involved in the development of novel methods of producing thermalized ions for use in TIMS instrumentation.

(U-Th)/He Thermochronology Lab

PI:  Rebecca Flowers

Equipment/Description:  The (U-Th)/He thermochronology lab contains an Alphachron quadrupole He system for automated degassing, isotope dilution and measurement of He. The facility includes a high-quality microscopy facility for mineral selection consisting of two microscopes and a camera system for photo-documentation of minerals for analysis. The lab routinely carries out all aspects of mineral separation, U-Th spiking and mineral dissolution, and U-Th analysis by ICPMS at CU-Boulder. We regularly analyze apatite and zircon, and are exploring the potential of other minerals for (U-Th)/He thermochronology.
