Photo de stock - Tecnalia Researchers carried out analysis by gas chromatography and mass spectrometry Gas chromatography is a separation technique based on the distribution of the components of a cross between a stationary phase and a gaseous mobile phase, while mass spectrometry is an analytical technique capable of an almost unequivocal identification as provides a characteristic spectrum of each molecule The union of gas chromatography mass spectrometry allows the separation, identification and quantification of volatile and semivolatile components of complex mixtures Food industry Biotechnology Laboratory, Health Area, Alava Technology Park, Technology Centre, Tecnalia Research & Innovation, Miñano, Araba, Basque Country, Spain
