Abstract

Zum Aufspüren von Leckagen in einer Vorrichtung, die eine Flüssigkeit enthält, wird ein Farbstoff in der Flüssigkeit gelöst. Die Vorrichtung wird von außen mit Licht im Spektralbereich um die Anregungswellenlänge des Farbstoffs bestrahlt. Eine Detektionseinrichtung weist Fluoreszenzlicht des Farbstoffs nach, welches an, auf oder in unmittelbarer Nähe der Vorrichtung auftritt. Die durch den Fluorophor markierte Flüssigkeit kann auf diese Weise gezielt nachgewiesen werden, wenn sie aus der Vorrichtung austritt. Dadurch wird ein auftretendes Leck schnell sichtbar.
