A Microelectrode for Measuring Intracellular pH1
A simple and reliable method of constructing an intracellular pH microelectrode is described. Antimony is used as the pH sensor. Antimony electrodes have been used in biological systems as early as 1927 (1). Since then several investigators have used different kinds of Sb electrodes. Roos and Boton (3) describe the latest methods of construction and application of pH sensitive micro-electrodes. In most cases the pH electrodes were fabricated by pulling glass capillaries filled with molten antimony and in a few cases by coating glass with antimony. The electrodes were of the open type.
