TL;DR: In this paper, pairs of enantiomers of nine aldoses were separated by gas-liquid chromatography on an OV-17 capillary column as the trimethylsilyl ethers of methyl 2- (polyhydroxyalkyl) -thiazolidine-4 (R) -carboxylates.

TL;DR: A simple, rapid, and highly sensitive high-performance liquid chromatographic method is described for the determination of N-acetyl- and N-glycolylneuraminic acids in human and animal sera, glycoproteins, and glycolipids.

TL;DR: A simple, rapid, and highly sensitive fluorometric high-performance liquid chromatographic method for the determination of N- acetylneuraminic acid and its mono-O-acetyl derivatives in human and rat sera is described.

TL;DR: The method was applied to the determination of the neuraminic acids in sera from normal subjects and cancer patients, normal urine and rat serum, where the limit of detection is 40 fmol (12 pg) for both neuramini acids in 10-microliters injection volume.

TL;DR: In this article, pairs of enantiomers of nine aldoses were separated on gas-liquid chromatography equipped with an SE-30 capillary column as trimethylsilyl ethers after conversion of the aldosing to methyl 2-(polyhydroxyalkyl)-thiazolidine-(4R)-carboxylates using the reaction with L-cysteine methyl ester.
