    Abstract: A device for equilibrating small quantities of a liquid reagent or a test solution with a gas-containing liquid or a gas in which at least part of the passage of the reagent leads through a hollow space that is separated by a permeable wall from a gas chamber which is closed, except for an inlet and an outlet opening, and which may be charged with the gas or gas-containing liquid. In order to ensure good mixing of the test liquid during equilibration, the hollow space carrying the liquid is configured as a tube or hose with one or more helical sections inside the gas chamber whose walls are permeable to the gas.

    Abstract: In order to produce a sensitive membrane electrode with high selectivity with respect to other anions and lipophilic ions or interfering substances, the membrane is based on an unplasticized polymer matrix whose content of electroactive component is between 50 and 90 percent by weight.
