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 7.0 (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.
Specifications are in Chapter 7.
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 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 host computer for its use. Unlike some other quartz
crystal microbalances, the instrument connects to the computer through a USB cable. 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.
