Abstract

A test cell comprises a test chamber at least partially enclosed by a wall. The test chamber holds a test fluid, and a test material is placed within the test chamber such that at least a portion of the test material is contact with the test fluid and at least a portion of the test material is in optical register with a window of the wall. A first conductive element is in electrical communication with the test fluid but is separated from the test material by a space, and extends to an outside of the cell. A second conductive element is in electrical communication with the test material and also extends to the outside of the cell.
