PCT No. PCT/GB88/00992 Sec. 371 Date Sep. 25, 1989 Sec. 102(e) Date Sep. 25, 1989 PCT Filed Nov. 14, 1988 PCT Pub. No. WO89/04958 PCT Pub. Date Jun. 1, 1989.An electrochemical reference element is proposed having a metal electrode such as silver coated with the tetraphenyl (TPB) salt of the metal. The element may form the internal reference of an ion selective electrode with an ion selective membrane carried directly upon the TPB coating. The element provides a thermodynamically reversible couple suitable for use in a non-aqueous environment.
