ABSTRACT:
An electrochemical cell for use in the detection and measurement of water soluble gases includes a vessel having a first chamber adapted to receive and contain said gas and having located therein a working electrode and a second chamber adapted to contain an electrolyte and having located therein a reference electrode arranged to be in contact with said electrolyte. A counter electrode is located in either the first or second chamber. The working electrode consists of an absorbent material communicating between said first and second chambers, which is adapted to be in contact with said electrolyte and has an electro-active substrate deposited on at least a portion of the surface of that part of the material located in the first chamber.
