Abstract
Abstract An electrochemiluminescent layer for use in apparatus for determining the concentration levels of pollutants in water by measuring the increase in light emission of a luminescent surface electrochemically excited by a supporting electrode surface, where a tris bipyridyl ruthenium complex forms a homogeneous mixture with a perfluorinated, sulfonated polymer film, deposited on a transparent, electrically conductive surface, in which case the surface may also have a fine-grained structure.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
71 words
An electrochemiluminescent (ECL) electrode for use in apparatus for monitoring the concentration of organic materials in water, comprising: (a) an ECL layer consisting of a homogenous mixture of a tris (2, 2'-bipyridyl) ruthenium complex and a polytetrafluoroethylene polymer backbone with pendant sidechains terminating with sulfonic groups, deposited on (b) an etched glass substrate layered with a light transparent, electrically conductive, fine grained substance for supporting and electrochemically activating said ECL layer.
Claim 2
Dependent Claim
