## Abstract A method for the direct identification of organic inclusions in graphite on the basis of field desorption mass spectrometry is proposed, based on the possibility of using a fractured graphite sample as a field emitter. Under such circumstances, the organic inclusions adsorbed on the sur
## Abstract Field desorption (FD) mass spectrometry was applied to the determination of the molecular masses of carotenoids, natural carotenoid derivatives and their chemical derivatives. All the carotenoids examined gave the molecular ion as the base peak with negligible fragment ions. Carotenoid
