An electrochemical carbon meter using liquid Na/sub 2/CO/sub 3/-Li/sub 2/CO/sub 3/ eutectic contained in a thin-walled iron membrane cup was constructed. A reference electrode was kept immersed in the electrolyte. The membrane cup assembly was dipped into static sodium for analysis. Carbon in sodium equilibrates with the iron membrane. An electromotive force was developed across the electrolyte due to the presence of a carbon activity difference and this was measured using a high impedance digital volt meter. The measured electromotive force was dependent on the type of reference electrode used in the probe. Further characterization of the reference electrodes is needed for the reliable operation of this type of carbon meter for sodium. However, graphite seems to fit best the requirements of materials for use as the reference electrode.
