Abstract

Die Erfindung betrifft ein Fotometer zur Messung von Gaskomponenten, mit einem Infrarotstrahler mit Strahlermodulation und einer Meßküvette mit Meß- und Vergleichskammer, einem auf die Gaskomponente X optopneumatisch absorbierenden, also mit X gefüllten Detektor. Um bei einem Fotometer dieser Art eine Mehrkomponentenmessung mit hoher Genauigkeit und möglichst geringem apparativen Aufwand zu ermöglichen, ist erfindungsgemäß vorgeschlagen, daß zur Messung mehrerer Gaskomponenten mindestens ein weiterer Detektor hinter dem ersten Detektor angeordnet ist, daß der weitere Detektor zur Messung der Gaskomponente Y mit seinem Isotop Y* gefüllt ist, und daß der erste Detektor hinsichtlich der weiteren zu messenden Gaskomponente Y* bzw. deren charakteristischen Absorptionsbanden optisch transparent ist.
