Abstract

Abstract Translated from German Zur Simultanmessung von zwei Parametern einer flüssigen oder gasförmigen Probe, in einer Fluoreszenzmeßeinrichtung bei wel­cher Einflüsse von Alterungsprozessen der Indikatorsubstanz und Schwankungen der Lichtstärke der Anregungslichtquelle ver­mieden werden sollen, wird vorgeschlagen, daß die Änderung ei­nes ersten zu messenden Parameters aus der Änderung des Ver­hältnisses zweier, bei unterschiedlichen Wellenlängen des An­regungs- oder Emissionsspektrums der Indikatorsubstanz be­stimmter Intensitätswerte und die Änderung eines zweiten Para­meters aus der Änderung der Abklingzeit t der Fluoreszenz­strahlung derselben Indikatorsubstanz aus der Gruppe der aro­matischen Kohlenwasserstoffe, der aromatischen Heterocyclen und der metallorganischen Komplexe gewonnen wird. For the simultaneous measurement of two parameters of a liquid or gaseous sample, in a fluorescence measuring device in which influences of aging processes of the indicator substance and fluctuations in the light intensity of the excitation light source are to be avoided, it is proposed that the change of a first parameter to be measured from the change in the ratio of two, at different wavelengths of the excitation or emission spectrum of the indicator substance of certain intensity values and the change in a second parameter from the change in the decay time t of the fluorescent radiation of the same indicator substance is obtained from the group of aromatic hydrocarbons, aromatic heterocycles and organometallic complexes.
