Requirements for Metal Samples
If you use a rectangular metal sample, it must measure at least 6 cm on each side. The sample must be flat
enough that a water-tight O-ring seal can be made.
The area to be tested must be within 2 cm of one of the edges on the sample. If it is farther away, the clamp
cannot hold the cell onto the sample.
The minimum sample thickness depends on the type of metal. Generally about 0.05 mm is a useful minimum
thickness. Samples between 7 mm and 15 mm thick require testing without the base.
Painted samples must have an area outside of the cell free from paint. This area is used to make electrical
contact with the sample.
Chemical Compatibility
The O-ring used in this cell is made from an ethylene/propylene elastomer. The top is made from a carbon-
filled natural rubber. These materials are not universally chemically resistant. They should give acceptable
performance with dilute acids, bases, and chloride salts.
We do not recommend use of the PTC1 with strong acids and bases, oxidizing or reducing
agents, or organic solvents. Gamry Instruments is not responsible for damage caused to the cell, your
laboratory, or your person by use of the PTC1 with an incompatible test solution.
