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

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 ┬Ám 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.

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.

For more information about our lab, or to submit samples for analysis, please contact Emily Verplanck.

(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.

Our facility is available to in-house and outside users. For more information regarding our lab and rates, please contact Becky Flowers or Jim Metcalf.
