Equipment


 
  • A combined gas chromatograph-mass spectrometer (GC/MS) system consisting of a VG 7025H-B105 double focusing magnetic sector mass spectrometer, a HP 5890A gas chromatograph, and a Kratos Mach 3 data system.
  • A Finnigan MAT 251 mass spectometer for stable carbon isotope analysis.
  • Two custom-made isotope prep lines with a LECO furnace and a Perkin Elmer 8500 gas chromatograph for natural gases, liquid and solid organic matter and carbonate samples.
  • Several capillary gas chromatographs which are configured with a variety of injection ports (split/splitless, on-column, packed column) and detectors (FID, FPD, TCD).
  • A Perkin Elmer HPLC system
  • A Perkin Elmer UV-Vis Spectrophotometer
  • A Rock-Eval II - anhydrous programmed pyrolysis.
  • A Hyrdrous Pyrolysis Laboratory.
  • Two Carlo Erba elemental analysers and one LECO Carbon analyser.
  • Data from the gas chromatographs, elemental analyzers and HPLC are collected and processed on PE Turbochrom 4 chromatography data system.
  • A Laboratory peer-to-peer local area network (LAN) which links the instrumentation with personal computers
  • An HP 6890 gas chromatograph with a split/split-less and packed column inlets and a flame ionization detector was installed in 1996.
  • A VG Optima mass spectrometer equipped with gas chromatograph and elemental analyzer sample introduction systems. The instrument can analyze stable isotopes of natural gases, liquid and solid organic matter.
  • Location: Denver.
