"Von Zucker und Wasser"

Grüne Zuckeranalytik für Jedermann // Beitrag aus der LABORPRAXIS 3-2019
Die Analytik von Zuckern reicht von der einfachen Bestimmung per Farbreaktion bis hin zur komplexen Quantifizierung mittels Massenspektrometrie. Wie die Zuckeranalytik per Hochleistungs-Flüssigkeitschromatographie (HPLC) gleichermaßen einfach wie „grün“ möglich ist, beschreibt diese Applikation.
