High-temperature gas chromatography and gas chromatography-mass spectrometry of glycoprotein and gly

High-temperature gas chromatography and gas chromatography-inass spectrometry for the analyses of oligosaccharides derived from glycoproteins or glycosphingolipids has been developed. Pcrmethylatcd oligosaccharides with up to about 12 sugar residues and masses up to 2500 Daltons can be analyzed. This approach is discussed and exemplified.
