Claims23
A method for reducing corrosion of an electrically conductive metallic layer during storage of an electrode comprising said electrically conductive metallic layer in intimate contact with an electrically conductive gel, said electrode being adapted for establishing electrical contact with the skin, wherein the access to oxygen is reduced or eliminated.
The method according to any of the precedent claims, wherein the concentration of inert or reducing gas in the atmosphere is 99% by volume or above.
The method according to any of the precedent claims, wherein the electrode is stored in a substantially gas-tight container.
The method according to clam 1, wherein the pH of the electrically conductive gel is between 0 and 4.
The method according to any of the preceding claims, wherein the electrically conductive metallic layer comprises tin, aluminium, zinc, lead, or silver.
A method for packaging an electrode comprising an electrically conductive metallic layer in intimate contact with an electrically conductive gel, said method comprises the steps of
- arranging the electrode in a substantially air-tight container,
- evacuating the container and/or providing in the container an atmosphere having a reduced concentration of oxygen compared to the concentration of oxygen in the surrounding air,
- sealing the container, whereby the electrode is provided in a substantially air-tight closure deprived of oxygen.
A container for storage having walls of an essentially gas-tight material comprising
- (i) an electrode comprising an electrically conductive metallic layer in intimate contact with an electrically conductive gel and
- (ii) an atmosphere having a reduced amount of oxygen compared to the amount of oxygen in the surrounding air.
