Well‐developed voltammetry with good reproducibility can be easily obtained without adding supporting electrolyte by use of a solid polymer electrolyte (SPE) composite microdisk electrode, which is made of a microdisk electrode and a SPE membrane. The measured current is dependent on the dissolution and transport rate of electroactive species in the SPE membrane. If the dissolution of the species in the membrane can be expressed by Henry's law, the current is proportional to the concentration of the species in organic solution. The linear relationship shows the potential applications of SPE composite microelectrodes in the analysis of the electroactive species in organic media.
