PCT No. PCT/GB95/00145 Sec. 371 Date Oct. 16, 1996 Sec. 102(e) Date Oct. 16, 1996 PCT Filed Jan. 25, 1995 PCT Pub. No. WO95/20050 PCT Pub. Date Jul. 27, 1995An amperometric sensor device comprising a working electrode, a reference/pseudo-reference electrode and a permselective membrane incorporating a charged organic species. The electrodes are in intimate contact with the membrane and are on a side of the membrane opposite to the side exposed to a fluid sample. The charged organic species provides a conducting path through the membrane between the electrodes.
