Regarding this thread:

http://www.pupman-dot-com/listarchives/2002/May/msg00914.html

I would like to perform some electrical resistivity measurements on a
specimen at a temperature of 77 K.  The resistance of the specimen is around
500 K ohms.  My plan is to affix electrodes to the specimen and dip it in
liquid nitrogen, then measure the resistance.

I think this will work O.K., but what about the liquid nitrogen?  Is it
conductive?  Would anyone know what the conductivity of LN2 is?


Thank you,
