Abstract

A gas-liquid chromatographic (GLC) method has been developed for the analysis of samples containing nanogram to picogram amounts of three different types of monosaccharides, viz., aldoses, ketoses and deoxy sugars. The minimum detectable amounts were at the sub-picogram level when highly electron-capturing derivatives such as trifluoroacetyl (TFA) esters of sugars were used. The gas chromatograph was modified to utilize the powerful combination of a glass capillary column and an electron-capture detector. For nine monosaccharides all of the anomers were resolved on a glass capillary column with particularly good deactivation properties. The losses of the TFA derivatives on the column were determined approximately at different carrier gas flow-rates. Quantitative determination was facilitated by taking all anomeric forms into account. The sensitivity and resolution of the method permit extremely small amounts of sugars in a complex mixture to be studied. This has been demonstrated on a sea-water sample.
