Method for analyzing gaseous or liquid samples, utilizing a one-way measuring element with a measuring channel containing at least one optical or electrochemical sensor and being provided with sealing elements on either end. In order to obtain accurate measurements in a simple manner the proposal is put forward that for measuring purposes a storage medium in the measuring channel be replaced by a separating medium which should then be replaced by the sample. Sample and storage medium will remain in the measuring element when it is discarded.

One-way measuring element for analyzing gaseous or liquid samples

A device for determining the concentration of at least one substance in organic tissue includes a subcutaneous needle for insertion into the tissue and a pumping and suction unit which is controlled by a microprocessor and is used for delivering a perfusion fluid and draining it after its partial equilibration with the tissue. The device further includes a sensing unit connected to the microprocessor for determining the concentration of the substance to be analyzed and one or more marker variables. The perfusion fluid, a calibrating solution and at least one drug are provided in replaceable metering ampoules sealed with membranes, whose metering plungers can be actuated by a drive unit controlled by the microprocessor. The metering ampoules communicate with a master capillary leading from the pumping and suction unit to the subcutaneous needle; communication is established via capillary tubes piercing the membranes.
