Improvement of reaction yield and chemical compound purity checks are typical control tasks in chemical synthesis quality control. Since speed is becoming increasingly important, commonly used techniques are becoming more and more overburdened. Thus, fast chromatography coupled with fast and reliable mass spectrometry is highly desirable.

Determining Carbohydrates in Essential and Non-essential Foodstuffs using Ion Chromatography

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 preparation such as dilution and filtration, samples with interfering matrices such as protein-containing dairy products have to be dialysed before injection.
