Bump.

If there is something like a list of chemically compatible fluids that have been tested that would be nice too.

Thanks,

Dave

Dave,

I would take a guess, Diiodomethane (CH2I2) should be chemically similar to Dichloromethane (CH2Cl2, also called methylene Dichloride). By looking up the chemical compatability list in the Appendix A of 004-1016-000 ELECTROCHEMICAL SPM MANUAL VERSION 7-C, methylene Dichloride is fairly compatible with the Dimension Fluid Cell.

 Chemical                           304 SS          316 SS              Epoxy                Gold/ Platinum                   Kel-F             PEEK            Silicone                  Teflon                   Viton

Methylene Chloride             B                  B                          A                        A                                        A                  A                    N/A                          A                            B

 A= Excellent.

B= Good-- Minor Effect, slight corrosion or discoloration.

C= Fair -- Moderate Effect, not recommended for continuous use. Softening, loss of strength,swelling may occur.

D= Severe Effect, not recommended for ANY use.

N/A= Information Not Available.
