Estimating the term…
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.
A one-way measuring element which is insertable into an analyzer for analyzing gaseous or liquid samples, wherein said one-way measuring element comprises a sensor part and a sample-taking part, said sensor part comprising a measuring channel with an inlet end, an outlet end and a measuring zone with at least one sensor located in said zone, said measuring channel being provided with seals on both of said ends and containing a calibrating and storage medium prior to measurement, and wherein a coupling element is placed at said inlet end of said measuring channel for direct coupling of said sample-taking part containing said gaseous or liquid sample, said measuring channel of said sensor part being sealed in the area of said coupling element by a first gas-tight diaphragm which is pierced by a sample channel of said sample-taking part, said sensor part further being sealed at said outlet end of said measuring channel by means of a second gas-tight, pierceable diaphragm wherein a collecting chamber is positioned between said measuring channel and said second gas-tight diaphragm, said collecting chamber comprises a reservoir for said calibrating and storage medium, and wherein said sensor part is connectable to a suction device of the analyzer after said second gas-tight diaphragm has been pierced, and wherein said outlet end of said measuring channel of said sensor part is provided with the reservoir receiving said calibrating and storage medium and wherein said calibrating and storage medium contained in said measuring channel is displaced by said sample flowing in after said sample-taking part is coupled to said sensor part.
A one-way measuring element which is insertable into an analyzer for analyzing gaseous or liquid samples, wherein said one-way measuring element comprises a sensor part and a sample-taking part, said sensor part comprising a measuring channel with an inlet end, an outlet end and a measuring zone with at least one sensor located in said zone, said measuring channel being provided with seals on both of said ends and containing a calibrating and storage medium prior to measurement, and wherein a coupling element is placed at said inlet end of said measuring channel for direct coupling of said sample-taking part containing said gaseous or liquid sample, said measuring channel of said sensor part being sealed in the area of said coupling element by a first gas-tight diaphragm which is pierced by a sample channel of said sample-taking part, and wherein said outlet end of said measuring channel of said sensor part is provided with a reservoir receiving said calibrating and storage medium, said reservoir configured as a balloon for cooperating with a squeezing mechanism in said analyzer, wherein a change in the shape of said balloon is accompanied by a volume enlargement of said reservoir.
A one-way measuring element which is insertable into an analyzer for analyzing gaseous or liquid samples, wherein said one-way measuring element comprises a sensor part and a sample-taking part, said sensor part comprising a measuring channel with an inlet end, an outlet end and a measuring zone with at least one sensor located in said zone, said measuring channel being provided with seals on both of said ends and containing a calibrating and storage medium prior to measurement, and wherein a coupling element is placed at said inlet end of said measuring channel for direct coupling of said sample-taking part containing said gaseous or liquid sample, and wherein said calibrating and storage medium contained in said measuring channel is displaced by said sample flowing in after said sample-taking part is coupled to said sensor part,
