The present invention is directed to membranes, sensors, systems and process for the detection of magnesium ions in protein-containing samples. The novel membranes, sensors, systems, and processes are based upon the discovery that the lipophilicity of the plasticizer (or blend of plasticizers) utilized in the formulation of magnesium ion selective membranes for clinical use is inversely proportional to the sensitivity of the plasticizer(s) and directly proportional to the use life thereof.

Magnesium ion selective membranes

Disclosed are internal electrolyte layers for ion selective electrodes, wherein the internal electrolyte layers contain carbon paste doped with a metal salt. Also disclosed are ion selective electrodes and sensor array assemblies containing the internal electrolyte layers. Also disclosed are methods of producing and using the internal electrolyte layers, ion selective electrodes, and sensor array assemblies.
