MEASURING INSTRUMENT SUITABLE FOR MEASURING CATIONS OR ANIONS, AND MEMBRANE AS PART OF THE MEASURING INSTRUMENT

摘要

The invention relates to a measuring instrument suitable for measuring cations or anions, comprising a measuring electrode contained in a housing, at least one wall of the housing being embodied as an ion-sensitive membrane made of a matrix material comprising an apolar ionoforic material. The matrix material is made of porous technical ceramics. The membrane is further provided with at least one substrate made of technical ceramics for feeding ionoforic material to the membrane. In addition, the invention relates to the membrane described as component of the measuring instrument according to the invention.
