In a twenty year old publication Yee and Chang suggested the use of molecular sieve pellets as a liquid junction for reference electrodes. It has the advantage that it does not dissolve in base the way Vycor(R) does.

Long awaited EIS textbook due soon!

A new textbook on EIS by Orazem and Tribollet is due at amazon.com July 21, 2008. Orazem has taken his lecture notes from the ECS short course on Impedance and organized them into a book. Since the ECS short course has been given several times, this promises to be a book one can learn from!

Complex Number Refresher

ISO and ASTM should both adopt XML formatting for EIS data files!

Online calculator: Estimating the True C from a Constant Phase Element

webmaster@consultrsr.com — Tue, 31 Jan 2006 14:02:39 -0400

A new online calculator has been added that allows estimating the "true" capacitance from a CPE. The equations of Hsu & Mansfeld are used to estimate C from omega(max) and the CPE parameters.

Inductance Calculator Updated

webmaster@consultrsr.com — Sun, 07 Aug 2005 06:54:27 -0400

Minor revisions have been made to the equations underlying the "Inductance Calculator." New references also have been added.

The calculator estimates the inductance of an isolated piece of straight, round wire. It can be used to estimate the inductance of our working electrode.
