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.

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.
