A process for operating an electrochemical measuring cell ( ) is described, with which it is possible to carry out gas concentration measurements already shortly after switching on the measuring cell ( ). The process includes the steps that potential voltage pulses are applied to the measuring cell ( ) in a state of readiness of the measuring cell ( ), in which the potential voltage is switched off. A system and device are also described.

Process for operating an electrochemical measuring cell

A holder for a test tube with a test robe tip that can be opened, with a tube, which accommodates the test tube at least partially, and whose tube end has a projection pointing toward the test tube tip in the area of the test tube tip. The handling steps needed to open the test tube are reduced by providing a projection beginning from the tube end, with a cross-sectional area decreasing continuously over at least a section. A displacement zone is provided between the projection and the test tube in such a manner that the projection can be brought into contact with the test tube tip upon pressure on the tube end.

A detection device with a gas detector element for analyzing pressurized gases contained in a reservoir by sampling while the pressure is reduced. A coupling means is provided for connecting the detector to a reservoir. Ease of handling is facilitated in the routine operation by providing a time-keeping device determining the duration of the sampling flow set at a preselected value. A switch starts the time-keeping device, and the switch is actuated at least at the time of the coupling of the detector to the reservoir.
