  • Publication number: 20250102492
    Abstract: A gas measuring device (100) and a gas measuring process measure a concentration of a component in a gas mixture (A), in particular the concentration of breath alcohol in a breath sample. The gas mixture (A) flows into a tubular input unit (1) which is detachably connected to a base body (6, 16). A portion of the gas mixture (A) is branched off and the gas sample (Gp) thus produced flows into a measuring chamber (2). A gas sensor (50) measures the concentration of the component in the gas sample (Gp). The gas sample (Gp) is branched off from the input unit (1) at an entry point (P.e) and re-enters the input unit (1) or a channel leading into the environment at a downstream exit point (P.a1). The measuring chamber (2) is connected to these two points (P.e, P.a1) by two different fluid guide units (3, 4).

  • Publication number: 20240011939
    Abstract: A sensor arrangement (100) and a process analyze a gas for at least one predetermined component and includes an electrochemical sensor (10) with a measuring electrode (20) and a counter electrode (21). An electrolyte (28) is arranged between the electrodes (20, 21). The process is carried out using such a sensor arrangement. A contact segment (7) of an electrically conductive measuring element (6, 7) is in thermal and/or electrical contact with a measurement object (20) (measuring electrode, counter electrode, or electrical contact). A connection segment (6) of the measuring element connects the contact segment to a temperature sensor (9) spatially distanced from the measurement object. The temperature sensor directly or indirectly measures the temperature of the contact segment, particularly the temperature of the connection segment. Depending on this measurement result, the temperature of the measuring electrode and/or the temperature of the counter electrode is determined and optionally controlled.

  • Publication number: 20230400476
    Abstract: An analyzer (100) and a process for analyzing a gas (G) for a predetermined substance. A sensor measures an indicator of the amount or concentration of the substance in a gas sample located in a measurement chamber (3). A movement of an actuating unit (4, 17, 19) in a first direction (R.1) increases the volume of a suction chamber unit (5). A movement of the actuating unit (4, 17, 19) in a second direction (R.2) decreases the volume of the suction chamber unit (5). A motor (7) rotates a cam disk (1) about an axis (MA). The actuating unit (4, 17, 19) is mechanically coupled to the cam disk (1). Each rotational position of the cam disk (1) relative to the axis (MA) determines a position of the actuation unit (4, 17, 19) and thus a volume of the suction chamber unit (5).

  • Publication number: 20230324263
    Abstract: An analyzer and a process analyze a breath sample exhaled by a subject for a predetermined substance, particularly alcohol. An input fluid connection connects an input unit (1) to a measuring chamber (3). A suction fluid connection connects the measuring chamber to a suction chamber unit (5, 6), that is selectively transferrable to a with minimum volume state or a maximum volume state. A sensor (12) measures an amount or a concentration of the substance in the measuring chamber. A drive unit (4, 11) moves a valve (2, 13) for the input fluid connection selectively into a closing or into a releasing end position. The drive unit can also move the suction chamber unit between the two states. The movement of the valve (2, 13) from one end position to the other end position is coupled with a transfer of the suction chamber unit (5, 6) between the two states.

  • Publication number: 20230221275
    Abstract: A gas measuring device (100) measures cyanogen in the presence of hydrogen cyanide. The gas measuring device (100) includes a measuring chamber (101), a heating element (103, 203) and an electrochemical sensor (105, 200). The measuring chamber (101) is configured to receive a sample. The heating element (103) is configured to thermally decompose cyanogen contained in the sample into decomposition products. The sensor (105, 200) is configured to detect the decomposition products of cyanogen, which are obtained by the thermal decomposition. A process measures cyanogen in the presence of hydrogen cyanide.
