Glucose liquid chromatography separation

Deliberate partial trimethylsilylation may be used as a means of distinguishing between various monosaccharides,199 and the nature of minor components formed on trimethylsilylation has been studied by mass spectrometry. Trimethylsilylation has been used in the separation of deuterated monosaccharides,200-203 and such deuterated trimethylsilyl derivatives as penta-0-(trimethyl-dliquid chromatography and mass spectrometry.143... 

In work on enzymic deacetylation, a series of D-glucose derivatives acetylated at specific positions was prepared, and the O-trimethylsilyl derivatives of these D-glucose acetates were separated by gas-liquid chromatography.352,353 Research on bacterial glycolipids required the characterization of 3- and 6-O-palmitoyl-D-glucose, the separation of which, as their O-trimethylsilyl and acetyl derivatives, was studied.354... 

Before discussing the various derivatives that have been used, it should be remembered that oligosaccharides are often obtained by chromatography on paper or on cellulose columns, and this may cause them to become contaminated by xylan this may be eliminated by extraction of the crude fractions with hot ethanol.474 For similar reasons, glucose that is really extraneous may be detected in fractions separated by electrophoresis on cellulose acetate.475 Gas-liquid chromatography was used to show the presence in pituitary glyco-...
