Abstract
The invention relates to an amperometric electrochemical cell having a first insulating substrate carrying a first electrode, a second insulting substrate carrying a second electrode, said electrodes being disposed to face each other and spaced apart by less than 500 μm, and defining a sample reservoir therebetween, and wherein at least one, and preferably both, insulating substrates and the electrode carried thereon include an electromagnetic radiation transmissive portion in registration with said reservoir. The walls of the electrochemical cell may be formed from a thin metallic portion on a transparent substrate. Such cells are useful in providing visual confirmation of the validity of the electrochemical measurement.
