The Gas Chromatography facility was created in 1988 in order to fulfill the needs of CIB-Margarita Salas and external users. This technique allows the separation, identification and quantification of volatile analytes.

Some routine analyses performed at the Chromatography Service are:

  • TMS derivatives/oximes of carbohydrates
  • Alditol acetates
  • Trimethylsilyl derivatives of several compounds
  • Volatile fatty acids
  • FAMES
  • Essential oils
  • Steroids
  • Polihydroxialcanoates

Other protocols can be set up on users demand.

Instruments
