  • Trimethylsilyl derivatives of several compounds
  • Volatile fatty acids
  • Essential oils
  • Steroids
  • Polihydroxialcanoates

Other protocols can be set up on users demand.



  • Gas chromatograph 7890A (Agilent) equipped with a Flame Ionization Detector, Thermal Conductivity Detector, autosampler (150 vials) and Headspace Sampler 7697A (Agilent).
  • Gas chromatography-mass spectrometry system (GC-MS) 7980A-5975C from Agilent for analysis of volatile samples of low molecular weight and autosampler (150 vials).
  • Sample Prep WorkBench 7696A (Agilent).
