Wir präsentieren eine bequeme Festphasen-Extraktion gekoppelt an Hochdruck-Flüssigkeitschromatographie (HPLC) mit elektrochemischen Detektion (ECD) für die gleichzeitige Bestimmung von drei Monoamin-Neurotransmittern und zwei ihrer Metaboliten im Urin von Säuglingen. Wir erkennen auch der Metabolit MHPG als potenzielle Biomarker für die Früherkennung von Schädigungen des Gehirns für Kleinkinder.
