The Basics of Electrochemical Impedance Spectroscopy: Part 1
4 Nov 2016This application note is a the first in a four-part series which explains the basics of Electrochemical Impedance Spectroscopy (EIS) and how it can be applied to the testing of batteries, fuel cells coating and corrosive reactions. This first part explains the AC Circuit Theory and the representation of complex impedance values. It goes onto describe how this data can be presented using Nyquist plots and discusses the linearity of electrochemistry systems.

pH Meters and ElectrodesIon and pH meters are electrochemical equipment used to measure the pH (acidity or alkalinity) or specific ion concentration of a solution. Other meters can also measure the conductivity or dissolved oxygen content of a solution. pH meters, specific ion meters, conductivity meters and dissolved oxygen meters can come as benchtop or portable equipment. A meter’s electrodes can be replaced with easy to clean electrodes or electrodes for difficult media. pH, ion and conductivity meters are typically used in life science research, pharmaceutical testing, food and beverage, environmental and water analysis.
