Résumé
Analysis of polysaccharides using the methylation technique has been aided by characterization and quantitative determination of derived O-methylalditol acetates by gas-liquid chromatography-mass spectrometry. Recent refinements in the technique include the use of capillary columns, which often results in better resolution of peaks. Recently, with the objective of analyzing microbial polysaccharides, the chromatographic behavior of O-methylalditol acetates arising from units ofgalactose, glucose, and mannose was examined on capillary columns of OV-17 and OV-225. In paralle1 and separate experiments with each column, it was found that several derivatives emerged in a different order depending on the column used. For example, the four tri-O-methylglucitol acetates that can be formed from glucopyranosyl units can be partly resolved on packed and capillary columns of OV-17, the 2,3,4 and 2,3,6
