Abstract
A conductivity cell wherein thin film or foil electrodes are supported in a case or holder and are separated by an electrically insulative spacer member. A small portion of each electrode together with an exposed surface of the spacer member forms a channel in which thin films of an electrolyte may be deposited from a measured environment and with the electrodes being connected to a conductivity circuit the conductance of the thin film may be measured. If the electrolyte and its concentration are known, the film thickness and deposition rate in the channel may be obtained.
Claims9
A conductivity cell for use in an environment which may include the deposition of thin films of an electrolyte, comprising:
- (A) an elongated holder having first and second elongated slots separated by a spacer member having a top surface portion susceptible to deposition of thin films of electrolyte;
- (B) first and second foil electrodes;
- (C) first and second electrode supports for respective support of said first and second electrodes;
- (D) said first and second supports being positioned within respective ones of said first and second slots;
- (E) said first and second electrodes being supported so as to extend beyond said top surface portion of said spacer member thereby forming a channel therewith, for said electrolyte deposition therein.
