Ion chromatographic analysis of carbohydrates
publication date: Dec 9, 2009
This article describes a straightforward ion chromatographic method that uses isocratic
elution and pulsed amperometric detection (PAD) to sensitively determine water-soluble
polyols and sugar alcohols as well as mono-, di- and oligosaccharides in essential and
non-essential foodstuffs. While carbohydrate determination of most foodstuffs requires
only minimal sample pretreatment such as dilution and filtration, samples with
interfering matrices such as protein-containing dairy products have to be dialyzed prior
to injection.
