Abstract

Abstract Translated from German Zur Verbesserung eines Einweg-Meßelements, welches zur Analyse von gasförmigen oder flüssigen Proben in ein Analysengerät einsetzbar ist und einen Meßkanal mit einem Meßbereich und zu­mindest einen darin angeordneten Sensor aufweist, wird vorge­schlagen, daß das Einweg-Meßelement (1) einen Sensorteil (2), an dessen Meßkanal (5) an beiden Enden Verschlüsse (8, 9;10;60) angeordnet sind, sowie einen Probennahmeteil (3) auf­weist, daß am eingangsseitigen Ende des Meßkanals (5) eine Kupplung (11), zur direkten Ankoppelung des die gasförmige oder flüssige Probe enthaltenden Probennahmeteiles (3) angeordnet ist, daß der Meßkanal (5) vor der eigentlichen Messung mit ei­nem Kalibrier- und Lagermedium gefüllt ist, sowie daß nach An­koppelung des Probennahmeteiles (3) an den Sensorteil (2) das im Meßkanal (5) enthaltene Kalibrier- und Lagermedium durch die einströmende Probe verdrängbar ist. Die dadurch erhaltenen Einweg-Meßelemente zeichnen sich durch einfachen Aufbau und benutzerfreundliche Handhabung aus. In order to improve a disposable measuring element, which can be used for analyzing gaseous or liquid samples in an analysis device and has a measuring channel with a measuring range and at least one sensor arranged therein, it is proposed that the disposable measuring element (1) include a sensor part (2) , on the measuring channel (5) at both ends of which closures (8, 9; 10; 60) are arranged, and which has a sampling part (3) that at the input end of the measuring channel (5) has a coupling (11) for direct coupling of the the gaseous or liquid sample-containing sampling part (3) is arranged such that the measuring channel (5) is filled with a calibration and storage medium before the actual measurement, and that after coupling the sampling part (3) to the sensor part (2) that in the measuring channel (5) calibration and storage medium contained can be displaced by the inflowing sample. The disposable measuring elements thus obtained are characterized by a simple structure and user-friendly handling.
