| Abstract: | By HCl-methanolysis of glycoconjugate, methyl glycosides are released. After trifluoroace-tylation they are separated on a capillary column and detected by electron capture detactor.Monosaccharide in samples of ganglioside GMI, glycoproteins and polysaccharide have been de-termined by this method. |
| Keywords: | Microdetermination of glycoconjugate Trifluoroacetylation ECD-GC |
