The Biomedical Mass Spectrometery Facility

The Biomedical Mass Spectrometry Lab supports clinical research projects in clinical nutrition and metabolic research.

Biomedical Mass Spectrometry Facility Unit Resources

  • Three gas-liquid chromatograph/mass spectrometer (GC/MS) systems, two of them are HP Mass Selective Detector (MSD) Systems (Models 5971A/5973A)
  • A Finnegan Delta-S isotope ratio mass spectrometer (IRMS) used for breath CO2 analyses, and hydrogen/oxygen analyses for the doubly labeled water method of determining energy expenditure.
  • ThermoQuest LCQdeca, this is a high pressure liquid chromatography/mass spectrometer (LC/MS) unit with the capability of a tandem mass spectrometer. The LCQ is used for small peptide quantitation sequence analysis and provides analytical support for investigators interested in clinical proteomics.
