โฆ Synopsis
The quantitative determination of individual hexoses in mixtures is of special importance for the elucidation of the structure of the oligosaccharide units of glycoproteins. Because of its high sensitivity we have been able to adapt the fluorometric procedure for glucose (l-3) to the continuous monitoring of effluents from Dowex 1 borate columns (4-6).
The method has been applied to hydrolyzates of a glycopeptide from orosomucoid containing galactose and mannose. The procedure as presently employed is completed in 4.5 hr and requires about 20 pg of each hexose.

The first practical method for the determination of hexosamines was worked out by Elson and Morgan (1). Since that time many modifications have been introduced in an attempt to increase the sensitivity and reproducibility of the technique (2) and to decrease the effect of interfering substances (3)
