Not much activity on this subject lately. Thought I would post a few PDF's which are useful. For my photodiode gamma detector experiments I believe in
extreme precision, excellent performance, meaning I like the LMP7721 3 femtoampere input current Precision OpAmp. So here is a little info on this
plus a couple documents about designing instruments useful in our experiments. So much can be gained by not choosing poor quality opamps. Edit to add
a Pspice model and a selection guide, plus a couple useful pages.

actualy its very interesting, because with conductivity measuring you can done some research on organic reactions kinetic and mechanisms, using simple
condutivity electrodes and data loger or chart recorder, but how to calibrate it for mS and mmS, with KCl?
