September 2007

 

It is September and two-thirds of 2007 is past! As our days get shorter we start to envy those of you in the southern hemisphere!

It doesn't matter if your days are getting shorter or longer, the outlook for electrochemistry is becoming brighter every day!

In this issue...

Reference Electrodes ...
Reference Electrodes

We finally took our own advice and appointed one SCE to be our Lab Master. We were surprised at how reproducible the SCE really is.

See our data and read about our attempts to resurrect abused Reference Electrodes.

 

Start Planning Now! 2008 Short Courses!
EIS Short Course

Gamry helps to sponsor two electrochemistry short courses, one on Corrosion Measurements and the other on Electrochemical Impedance. Both courses have been well attended in the past, and we expect them to fill up again in 2008!

Start planning your 2008 budget and travel schedule now!

 

Gamrarians speak at ASTM Symposium
ASTM Symposium Talks

David Loveday and Bob Rodgers both spoke at the ASTM G01 Symposium in May in Norfolk, VA, "Advances in Electrochemical Techniques for Corrosion Monitoring and Measurements." Copies of their slides are available. David spoke about the EFM Technique and Bob spoke about Reference Electrodes.

 

Happy Birthday Mr. Potentiostat!
Birthday Cake

Our breathless rendition of "Happy Birthday" may not be as impressive as when Marilyn Monroe sang it to JFK, but the three-electrode Potentiostat is 65 years old this year!

The Bunsen Colloquium is celebrating with a colloquium "65 Years of Potentiostats" in November in Dresden Germany.

Compliance Voltage. How Much is Enough?
Compliance Voltage

The compliance voltage of a potentiostat is the maximum voltage that the potentiostat can apply to the Counter Electrode in order to control the electrochemical cell. It is generally measured as the difference between the Counter Electrode and the Working Electrode. Most potentiostat manufacturers include the Compliance Voltage as one of the significant specifications in their data sheet.

Compliance Voltage is also one specification that users consider when purchasing a potentiostat. Although it is tempting to think that "The higher the better," a high compliance voltage is not without its price. The higher compliance voltage is, the higher the power requirements are within the potentiostat. Higher power means more complexity, more weight, and generally higher cost. The frugal electrochemist asks "How much compliance voltage do I really need?"
