  • Abstract Ceramides may be subjected to direct separation and structural study by gas phase analytical methods. Suitable derivatives may be prepared by reaction with silylating reagents (leading to trimethylsilyl ether derivatives), and separations may be carried out with 1% SE-30 columns by temperature programming at 2°/min to 340–350°C. The structure of individual ceramides is indicated by their mass spectra; both the acyl group and the sphingosine base moiety can be recognized in this way.
