Thermal Ionization Mass Spectrometer

A Micromass Sector 54 thermal ionization mass spectrometer equipped with one fixed and six movable faraday buckets, 20 bead turret, an ion counting Daly detector, negative ion capability, and complete automation system along with standard filament fabrication and degassing equipment, and clean air stations.

Noble Gas Mass Spectrometry

A MAP-215-50 noble gas mass spectrometer used for 40Ar/39Ar analyses.  Samples are transferred to the mass spectrometer through an automated extraction line with a Modifications Ltd. resistance furnace and CO2 IR laser.

An Isotopx NGX multi-collector mass spectrometer will be installed in early 2020 along with a new automated extraction system and CO2 IR laser.

The (U-Th)/He laboratory houses a noble gas extraction and purification system for 4He abundance measurement. The major components of the system are (1) diode laser gas extraction module with X-Y stage, (2) precisely calibrated volume aliquot of 3He for isotope dilution, (3) precisely calibrated volume aliquot of 4He for spike volume calibration, (4) gas purification module with Janis cryogenic trap and NP10 getter, and (5) Pfeiffer-Balzer Prisma quadrupole mass spectrometer.

Clean Laboratory

A metal-free laboratory with HEPA-filtered air under positive pressure and seamless flooring is used for sample processing for isotopic and selected trace element analyses.  This laboratory has all polypropylene clean air exhaust hoods for sample dissolution, reagent preparation, and column work.  Blank levels are more than adequate for the proposed research (e.g., <5 pg for Pb).

X-Ray Analysis
