Lipophilic salts as membrane additives and their influence on the properties of macro- and micro-electrodes based on neutral carriers
The influence of salts containing lipophilic cations and anions on the electrical resistance of the membranes of calcium ion-selective macro- and micro-electrodes based on a neutral carrier is described. The resistance of macroelectrodes was decreased by a factor of about 50 or of about 3 compared to membranes without and with potassium tetrakis- (p-chlorophenyl)borate, respectively. No significant reduction of the membrane resistance was achieved for microelectrodes. The lower detection limit and the Ca2+/K+ selectivity factor were improved for both types of electrode. © 1985.
