The Gas Chromatography service was created in 1988 in order to fulfill the needs of CIB 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 of carbohydrates
• Alditol acetates
• Partially methylated alditol acetates
• Butylglycosides
• Anhydroalditols
• Trimethylsilyl derivatives of several compounds
• Volatile fatty acids
• FAMES
• Essential oils
• Esterols
• Chlorobenzoates
• Polihydroxialcanoate

Other protocols can be set up on users demand.

Instruments

• Gas chromatograph 7980A (Agilent), equipped with a flame ionisation detector and autosampler for 150 vials.
• Gas chromatography-mass spectrometry system (GC-MS) 7980A-5975C from Agilent for analysis of volatile samples of low molecular weight.
