Zusammenfassung

Eine flüssige Nahrungsmittelprobe wird nacheinander über einen Kationen-, einen Anionen- und einen Kationenaustauscher perkoliert. Die Zucker und die Säuren werden abgetrennt und im Eluat der zweiten bzw. dritten Austauschersäule gefunden. Ein Steuergerät schaltet auf Zeitbasis eine Gruppe von Pumpen und ein System mit pneumatischen Hähnen derart, daß in einem Cyclus (50 min) die Substanzen eluiert und die Säulen regeneriert werden. Anschließend werden die Proben verarbeitet. Einige Ergebnisse verschiedener Nahrungsmittel werden angeführt.

Summary

In the gas-chromatographic analysis of sugars and acids in foodstuffs, isolation and purification of the two types of components is time-consuming and laborious. An automated clean-up procedure, based on ion-exchange, has therefore been developed. A liquid food sample is successively percolated over a cation and anion and a cation exchanger. Sugars and acids are collected under the second and third column, respectively. A time programmer operates a set of pumps and a pneumatic valve system enabling simultaneous regeneration of columns not being eluted. Hence, handling of samples is continuous; each clean-up cycle takes 50 min.
