Abstract

In order to improve a one-way measuring element, which may be inserted into an analyzer for analyzing gaseous or liquid samples and which comprises a measuring channel with a measuring zone and one or more sensors located therein, the proposal is put forward that the one-way measuring element be provided with a sensor part whose measuring channel has seals on both ends, and with a sample-taking part, and that a coupling element be placed at the inlet end of the measuring channel for direct coupling of the sample-taking part containing the gaseous or liquid sample, and that the measuring channel be filled with a calibrating and storage medium prior to the measuring process, and that the calibrating and storage medium contained in the measuring channel be displaced by the sample flowing in after the sample-taking part has been coupled to the sensor part. The one-way measuring elements obtained in this way are characterized by great simplicity of design and ease of handling.
