Abstract

An isocratic ion chromatographic procedure for the determination of monosaccharides from the hydrolysis of trace amounts of glycosides present in grape musts is described. A laboratory-made ultramicroband. electrode, tested previously with reference compounds, was used in the pulsed amperometric detection of the recovered sugars. The very low detection limits (lower than 1 mg/l) allowed the identification of xylose (not previously detected in grape musts) and apiose. The correctness of using the peak height as the measurement of the sugar concentrations also for partially overlapped peaks was checked by a deconvolution procedure based on the simplex method.
