Abstract Gas chromatography and the 20 eV mass spectra of the human milk oligosaccharides fucosido-galactose, fucosido-lactose, di-fucosido-lactose, 3'-N-acetylneuraminyl-lactose, 6'-N-acetylneuraminyl-lactose and of N-acetyllactosamine as pertrimethylsilyl (TMS) ethers are described. The gas chromatographic separation of the L-fucose containing oligosaccharides was performed on Silicone SE 30. The sialic acid containing sugars were separated on DEXSIL 300. The correlations between oligosaccharide structures and mass spectrometric fragmentation pat­ terns are discussed.
