Page 8: Introduction
Order your reference electrode separately. The ParaCell uses the two end plates and one of the four standard ports to implement its required functions. You can customize the cell by rearranging some of Gamry’s standard fittings or making or buying additional... -
Page 9: Chemical Compatibility Of The Paracell
Contact Gamry Instruments, if you need help selecting the proper replacement fittings. Gamry’s Paracell was not designed for use in electrolytes that dissolve glass (extremely basic solutions or HF containing solutions) or organic solvents which could damage the polycarbonate body. Be aware that some biological molecules will “stick”... -
Page 10: Unpacking And Checking Your Paracell
Unfortunately, no matter how carefully glass pieces are packaged, damage will sometimes occur. When you first receive your ParaCell kit, please check it for any signs of shipping damage. Be especially careful if the shipping container shows signs of rough handling. -

Unpacking and Checking Your ParaCellParts List Parts List Please check the contents of your kit versus the ParaCell packing list in Table 1. When shipped, all of the ParaCell components should be labeled with their Gamry Instruments, Inc. part number. -
Page 12: Assembly
If you are assembling your ParaCell for the first time, you may want to check for leaks after assembly. Because this cell is not designed to be pressurized, this is most easily accomplished by adding a small amount of dye to water, filling the cell, and setting it on some paper towels. -
Page 13: Main Cell Assembly
Figure 1 Assembled Cell (See Table 1 for Labels) The ParaCell includes a number of ACE-Thred™ connectors used for a wide variety of functions. #7 ACE- Thred™ connectors are particularly common. ACE-Thred™ fittings are designed to seal cylindrical objects into the cell. -

Make sure that the plastic “hats” are properly seated so that the metal rods nor nuts are in contact with the metal of the end bracket. Finger-tightening is generally sufficient to prevent leaks. -

(normally the red/orange side). The graphite plate that is shipped with your ParaCell is spectroscopic grade. It is very pure and is therefore unlikely to be a significant source of contamination in your initial experiment. However, it is somewhat porous and can adsorb substances present in your test solution. -

Gas Dispersion Apparatus In the ParaCell, gas-flow control apparatus is not included. Outlined is one way to handle gas flow. Use a thin flexible tubing (PTFE or other) for the gas feed line. With the cell assembled, run the feed line in through the angled, threaded access port on the counter side. -

Working Electrode (Sample) Because the working (and counter) electrodes form the end seals for the ParaCell, they must be in place prior to filling the cell with test solution. Take great care to insure that the surface of your test sample is not altered prior to the test. -
Page 18: Sample Masking
Electrode Connections: CorrosionSample Masking The ParaCell is designed for use with flat samples that are conductive through the sample—from the solution interface to the back wall, in contact with the leveling sample bracket. When this is the case, the banana jacks in the brackets can be used for electrical connection to the potentiostat. -
Page 19: Electrochemical Noise And Galvanic Corrosion
Electrochemical Noise and Galvanic Corrosion The ParaCell was designed to work for a wide variety of experiments, but it is ideal for galvanic corrosion and noise experiments. These are ZRA (Zero Resistance Ammeter)-mode corrosion experiments that measure the current passed between two electrodes of equal size. -

Following each problem is a list of some possible causes for that problem. Neither the list of problems nor the list of their causes is comprehensive. - Page 22 TroubleshootingAddition of a pH Electrode • Contaminants are entering the cell from the graphite counter electrode. • Your electrochemical system is inherently irreproducible; often true of localized corrosion phenomena.
