Abstract

The present invention provides a planar reference electrode (10) comprising: a substrate (20); an electrode connecting part (24); an electrode (22); an internal reference layer (23); a micro porous polymer membrane (38) which functions as both a junction and a protection membrane layer made of micro-porous organic polymeric membrane, characterised in that the internal reference layer further comprises; a hydrophilic bulk (26) made of bulk hydrogel layer containing organic internal electrolytes; a photo hydrophilic (28) layer conditioned with internal electrolyte; a hybrid solgel (30) which functions as junction between internal electrolyte and a bridge salts; a hydrophilic bulk (32) which is bulk hydrogel containing the bridge salts; a photo hydrophilic (34) which is conditioned with the bridge salts; a hybrid solgel (36) which functions as junction between external analyte and the bridge salts, wherein the at least two layers of hydrophilic hydrogel consisting of an electrolyte preferably ionic liquids selected from the group of hydrophilic chloride.
