Gas Chromatography - Mass Spectroscopy

Expert Volatile Compound Identification

What is GC-MS?

Gas Chromatography-Mass Spectroscopy (GC-MS) is used to identify and quantify volatile organic compounds within a sample. It works by breaking down samples into their components, separating them in a heated column, and analyzing each component with a mass spectrometer. This is especially useful for deformulation of polymers, material characterization, and contaminant identification.  FAI Offers GC-MS with three sampling techniques: Pyrolysis, Dynamic (or Static) Headspace, and traditional Liquid Injection.


FAI operates two HP 5890 Series II Gas Chromatographs coupled with an HP 5989B Mass Engine. We have three autosamplers:

  • HP 7673 Liquid Autosampler
  • Teledyne Tekmar HT3 Static and Dynamic Headspace Autosampler with a maximum temperature of 300°C
  • CDS Analytical Pyroprobe 2000 Pyrolysis Autosampler capable of heating samples up to 1,400°C

FAI also has access to exstensive mass spectra libraries for confident compound identification.


We test both solid and liquid samples. The solid samples are prepared in quartz rods for Pyrolysis GC-MS or 20mL headspace vials for Dynamic Headspace Concentration GC-MS. The liquid samples are prepared in 2mL vials.


FAI provides mass spectra data as well as chromatograms for complete chemical material characterization.
