Three reference electrode systems, Li-Al vertical bar Li/sup +/, Ni vertical bar Ni/sub 3/S/sub 2/ vertical bar S/sup 2 -/, and Ag vertical bar Ag/sup +/, are described briefly and evaluated on the basis of experience gained during about 200,000 test hours. The Li-Al vertical bar Li/sup +/ system has been selected as the primary standard because of the convenience of in situ calibration and the availability of a technique that unmistakably manifests the standard condition of the electrode. The Ni vertical bar Ni/sub 3/S/sub 2/ reference electrode is extremely stable, with slow potential shift of no more than +- 2 to 3 mV during thousands of hours of operation. The short-range stability (less than 100 hours) is +- 0.1 mV. Advantages of the Ag vertical bar Ag/sup +/ membrane electrode system are the perfect chemical isolation from the rest of the cell and the possibility of miniaturization by means of 0.5- to 1.0-mm-OD Pyrex capillaries.
