Abstract
Ion sensitive electrodes particularly for use at high temperatures and pressures are described. The electrodes can either include finely divided ion sensitive material in a matrix of low conductivity material, or a thin sheet of a naturally occurring ion sensitive material such as a mica or a silicate. The finely divided ion sensitive material may be an ion sensitive glass. Various forms of electrodes some including reference electrodes are described.
Claims32
Ion sensitive electrode means, including a matrix of low conductivity material containing particles of an ion sensitive material selected from the group consisting of a finely divided ion sensitive glass and a finely divided mica, the ion sensitive material having an outer hydrated layer thereon, and contact means for allowing direct electrical coupling with the interface formed when the matrix is in contact with a liquid.
