Chapter 2 -- Introduction
About this Manual
This manual covers the installation, safety, and use of the eQCM 10M Impedance Scanning Electrochemical
Quartz Crystal Microbalance.
This manual describes use of an eQCM 10M with Revision 5.62 (and later revisions) of the Gamry Resonator
software.
Chapter 1 was an in-depth discussion of safety issues. This chapter describes this manual and gives a brief
overview of the eQCM 10M features. Chapter 3 is a description of the electronics circuitry in the eQCM 10M.
Chapter 4 contains installation instructions. Chapter 5 describes inserting a crystal into a holder and connecting
the holder to the eQCM 10M and Chapter 6 describes the eQCM 10M’s Front and Rear Panels.
You will find specifications in the Appendix.
This manual does not discuss software installation or software operation in any detail.
Software support for the eQCM 10M is described in the Gamry’s On-line Help system and associated
documentation.
About the eQCM 10M
The eQCM 10M is a research grade electrochemical instrument packaged in a small, easy to handle case. It
offers measurement capabilities similar to instruments that are more than ten times its size and weight and
more than two times its price. The instrument can operate as a stand-alone quartz crystal microbalance or in
conjunction with a potentiostat.
eQCM 10M features include:
• 1 – 10 MHz operating range with no need to send the unit back to the factory in order to recalibrate
for different frequency crystals
• DC-decoupled output for interface with a potentiostat
• 0.02 Hz resolution
• Reporting of both the series and parallel resonance frequencies
• An insulated USB connection avoiding ground loops
The eQCM 10M, like all Gamry instruments, requires a computer for its use. Unlike some other quartz crystal
microbalances, the instrument interfaces to the computer through a USB connection. The USB connection has
become truly universal, with USB ports found on all modern computers.
Notational Conventions
In order to make this manual more readable we have adopted some notational conventions. These are used
throughout this manual and all other Gamry Instruments manuals:
• Numbered lists. A numbered list is reserved for step-by-step procedures, with the steps always
performed sequentially.
• Bulleted list. The items in a bulleted list, such as this one, are grouped together because they represent
similar items. The order of items in the list is not critical.
• File names and folders. Inside paragraphs, references to computer files and Windows folders will be
capitalized and placed within quotes, for example: “C:\MYGAMRYDATA\EQCM.DTA" and
“GAMRY5.INI".
