Abstract
A device and a method are disclosed for determining ion activity in liquids by the use of electrodes, particularly comprising an electrode mounting frame and transport means for promoting ionic migration between electrodes in the frame. Preferably, such electrodes are ion-selective electrodes.
Claims33
A device useful for determining the activity of ions in a liquid solution, comprising:
- a frame capable of being processed by automatic handling devices,
- two solid electrodes mounted with respect to said frame, each comprising a first operative layer coated over at least one other operative layer, said layers terminating at edges,
- means for providing ionic flow between said electrodes upon application of one or more liquid drops, and
- at each electrode, anti-shorting means for restraining the liquid from simultaneously contacting the edges of both of said layers.
