Interactive Electrophysiology Software
for Research and Teaching
MemPotW, ArtMemW and MemCableW are computer-aided learning programs aimed to simulate actual experiments and teach some difficult concepts in electrophysiology.
They are available as Windows 32 and 64-bit programs which may be run on Macintosh systems provided they have fully compatible Windows emulation packages.
Liquid Junction Potential Calculator (JPCalcWin) is a new stand-alone program redeveloped for 32/64-bit Windows by E. Crawford of UNSW from revised and extended MSDOS C++ JPCalc source code, in consultation with P H Barry.
A special upgrade path is now available for researchers who have purchased JPCalcW.

An author preprint of the following paper, which both describes an optimised technique to measure liquid junction potentials and also validates their calculation by the Henderson equation used by the above programs (for monovalent salts and the limited addition of divalent ions), is available at 2013Barry_etal-EBJ&ESM2013-hq.pdf

- Ionic Mobility Tables The tables in this listing give lists of the ionic mobilities stored in the Junction Potential Calculator programs, JPCalc, JPCalcW and the new JPCalcWin, together with more recent additional ionic values and references for further information. (last updates October 2003)
