Kind of ion-selective membranes used in an ISE comprising synthetic cross-linked polymer with fixed sites or thin glass membrane.
Note: The chemical composition of the polymer (e.g. polystyrenesulfonate, sulfonated poly(tetrafluoroethylene), poly(vinyl chloride) aminated) or the glass determines the membrane selectivity (see pH-sensitive electrode).
Example: Synthetic cross-linked polymer or glass electrodes
