LABORATORIES AND INSTRUMENTS

Pagani Biogeochemistry Laboratory

Pagani's Biogeochemistry Wet Laboratory is equipped with a Trace 2000 gas chromatograph with a flame ionization detector, a Thermo DSQ quadrupole mass spectrometer for compound identification, and an autosampler.  A Dionex ACE-300 in conjunction with two Zymark Turbo evaporators allows for rapid sample processing and high sample throughput. 

Isotope Ratio Monitoring Mass Spectrometer

Our IRM-GC/MS is housed in the Earth System Center for Stable Isotopic Studies (ESCSIS). Currently, ESCSIS maintains 4 stable isotope ratio mass spectrometers with a variety of off- and on-line sample preparation systems.  Our Finnigan MAT 253 stable-isotope mass spectrometer is equipped with a dual inlet, a gas chromatograph (Trace 2000)-combustion interface for the determination of carbon- and hydrogen isotope abundances on individual organic compounds, and a Hydrogen Device for analysis of D/H ratios of water. 

The other mass spectrometers in the

ESCSIS include Dr. Ruth Blake’s Delta XP with a Costec elemental analyzer, TCEA, and a Gas Bench II for carbonate and water analyses, and Dr. Danny Rye’s Finnigan MAT 251, dedicated to water and carbonate measurements. A second Delta XP is associated with a Costec elemental analyzer and is dedicated to bulk organic carbon and nitrogen analysis.
