A reference half-cell for use in a potentiometric measurement cell (2) for determination of ionic activity in a measurement solution (7), where the reference half cell consists of an electrode element (9) and a bridge electrolyte (8), where cell has an electrode body (5) electrical contact with solution (7), and the bridge electrolyte is a gel containing the electrolyte, i.e. a cationic gel based on diallyldimethylammonium chloride (DADMAC). Independent claims are included for: (1) the bridge electrolyte for use in the cell, which is connected to a potentiometric measurement element, which measures the ion concentration in solution (7); (2) a process for synthesis of a bridge electrolyte comprising a cationic gel based on DADMAC, where in a first step linear DADMAC-copolymer of predetermined concentration of reactive functions is synthesized, and in a second step the reactive linear copolymer is crosslinked with multifunctional agents. |
