Abstract
There is provided a novel type of ion selective membrane comprising a non-ion selective carrier, and an ion selective active phase molecule having a hydrophilic segment and a lipophilic periphery. In the preferred embodiment said molecule is a siloxane molecule whose Si-O-Groups are open chain, branch chain or cyclically oriented. These ion selective membranes are useful in the selective detection of alkali- and alkaline-earth metals. There is further provided an electrode for use with such a membrane.
