Abstract
Monosaccharides are the simplest form of carbohydrates and may be subcatagorized as aldoses or ketoses. The sugar is an aldose if it contains an aldehyde functional group. A ketose signifies that the sugar contains a ketone functional group. The purpose of this chapter is to analyse the gas chromatography separation of monosaccharides, amino sugar, sugar alcohol and reduced sugar. Mass spectra of TMS derivatives of sugars are also included which focuses on molecular weight, fragmentation. By plotting mass chromatograms for the m/z value of the M+• peak and the accurate m/z value 362.1639, the presence of these amino sugars can be determined. Chemical ionization using ammonia as reagent gas establishes the molecular weights of sugar acetates.
