The Quartz Crystal Microbalance
(QCM)
is an exciting new tool for the electrochemist. With it, the researcher
can now follow not only the current that flows, but the weight changes of
the electrode, too! This is a valuable tool when studying reactions which
involve films, adsorbates, metal deposition, corrosion, or monolayer
formation. It is sensitive enough to detect a fraction of a
monolayer of most materials.

Electrochimica Acta had a recent
volume (July 2000) which focused on the QCM in electrochemistry.
If you are just starting out, these

An 'A' pages article. this gives a
quick overview of the topic. Dan Buttry was among the first to use the QCM to study
electrochemical processes.

This 'A' pages article presents a summary of the
commercially available QCMs at the time.

This monograph is a good overview
of the capabilities of the method and an introduction to the
instrumentation as well. Many have used the "Buttry"
designed oscillator circuit which is given in the text. |
