ABSTRACT:
Devices and methods for providing electrochemical cells are disclosed which can be used in virtually any gaseous or liquid environment to make electrochemical determinations. The electrochemical cell comprises a microelectrode and a large reference electrode which are positioned a very short distance apart. The space between the microelectrode and the reference electrode is filled with a highly resistant material which has been treated (or otherwise provided) with an ionic substance. In use, the ionic substance associated with the resistive material acts as an immobilized ionic solution in much the same way as an electrolyte in a conventional electrochemical cell. However, the relative size and positioning of the microelectrode and the reference electrode overcame the problems of the prior art so that sensitive, accurate measurements can be obtained in both gas and liquid phase electrochemistry.
