Economical Potentiostat
If you want to do electrochemical measurements with a specific purpose in mind, you may need an economically priced potentiostat. PalmSens has several attractively priced instrumen...
Cyclic voltammetry
Cyclic voltammetry is a known method of demonstrating the presence of a substance in a given liquid by drawing a graph with a characteristic wavy line. The graph has a typical, rec...
Compliance voltage
The compliance voltage is the maximum voltage that can be applied between the working and counter electrode. Another name could be the maximum cell potential. ...
Biosensor
A biosensor is a sensor exploiting a biomolecule and is used to measure the presence of a certain substance in a liquid. For example, the medical world uses biosensors to detect a ...
Anodic Stripping Voltammetry
Anodic Stripping Voltammetry is a method to demonstrate the presence of multiple metals in water. This method is usually applied to investigate the water quality of sewage, surface...
EIS Corrosion Package
PStouch tutorials
With PStouch you can connect your Android smartphone or tablet via USB or Bluetooth to your instrument. The following tutorials explain how to connect to your instrument, how to ...
Electrochemical enzymatic biosensors
Do you want to make your own biosensors? How to immobilize the enzymes? Or are you wondering how to measure using a biosensor in a convenient and portable way? Lutz Stratmann gav...
List of symbols for corrosion research
Here you will find all the symbols used used by us in this knowledge base. Please note that other publications might use different symbols for the same parameters. ...
Coating Research in Food Industry
In this section it is explained why Electrochemical Impedance Spectroscopy (EIS) is a suitable technique to perform research on coatings meant for food storage. Furthermore, it wil...
Rapid Electrochemical Assessment of Paint
Many coating are still measured by exposing them for months with salt spray. The Rapid Electrochemical Assessment of Paint (REAP) allows within 24 hours to determine the Time To Fa...
Constant Potential vs OCP or vs Reference Electrode
There is sometimes confusion about the option to measure versus Ecorr / OCP and versus the reference electrode. In this section the reasons for choosing a certain DC potential is ...
How to fit easily
Sometimes fitting software just doesn’t seem to work properly and the fit values aren’t even close to the measured values. This can be due to bad starting values for the fit. I...
Equivalent circuit fitting for corrosion measurements
Understanding the Impedance Spectrum with a Bode or Nyquist and a few simple electronic components often doesn’t suffice. In this section of the handbook the Warburg Impedance an...
Bode and Nyquist Plot
In this chapter the two main ways of visualizing Electrochemical Impedance Spectra (EIS), the Nyquist and Bode plot, are presented and it is explained how different EIS of easy ele...
Tafel Plot and Evans Diagram
To understand the foundation of corrosion current measurements the Tafel plot and the Evan’s diagram are explained. The connection between a polarization curve and the Evan’s d...
Corrosion current
In this article the corrosion current, a fundamental parameter in corrosion research, is introduced. ...
Corrosion Potential
In this chapter the Open Circuit Potential (OCP) and the Corrosion Potential are introduced. The principles of reference electrodes as well as the 0 V by convention potential of th...
