Four Point Probe with Solartron

[lresteban]

Hi to everyone,

I would like to know if it is possible to perform four probe analysis with the Solartron 1260 FRA.

Thanks,

Lander

Yes, but FRA itself is not enough to do any testing, you need a potentiostat/galvanostat,

and that is what will provide a 4-probe interface.

Regards,
Yevgen

I use the following equipment:

Solartron Analytical 1260A impedance gain/phase analyzer
Solartron Analytical 1287 potentiostat/galvanostat
Solartron 12962 sample holder
Custom built EIS sample holders from BAM in Germany

Actually you can do 4-point measurements with just a 1260 but not with a 1255, However it is much more practical to use a 1287 in combination,
as you then have mush better control of the polarisation as well as amplitude of the AC. We have done many 4-point AC measurements using only 1260's without trouble as long as you know your geometry.
You just have to use the V1 or V2 input in combination with the current input and generator output and use V1/I or V2/I as source mode depending on which of the 2 inputs you use.
One thing you have to remember though is to correctly connect all the screens of all wires near your sample so that you do not get inductive cross coupling between the source wires and the sense wires. An additional concern is that the sense (I) input measures between the center and screen, thus you have to connect the screen wires of the generator and current input so that the return current from the sense input can run in the screen.

Hi,

  How are you all the members. I need one of the article from Seitz M, Hampton F, Richmond W. In: Yan MF, Heuer AH, editors. Advanced in ceramics, vol.7. Ohio. the american ceramic Society Inc., 1983. PP. 60-70. I also want to ask that some one can guide me that of the imaginary part of impedance broaden and shifts to lower frequency then what mechanism are involved. Hopefully i will get some good answers. I will wait for the reply.

Thanks,

Hi,

   Is it possible to perform four probe measurement with Solartron 1255B FRA, 1287 potentiostat and 1296 dielectric interface? 

Regards

Ramsundar.

Yes, it is, at least with the 1287 + 1255B combination (I have not used the 1296 myself)

[Aniruddha Kulkarni]

As suggested by Soren, you can definitely use 1287 + 1255 combination.

You can either use 1287 + 1255 combination or 1296 +1255 combo. 1296
is suited for very high resistance samples like "insulators", and it
can provide a voltage bias up to 40 V subject to signal amplitude
selection (check the specs on your manual).

I am not sure; but I don't think it would not take an additional
external bias from 1287 or similar (nor do I understand purpose of
doing so).
