Gamry Instruments, Inc. designs and manufactures a wide
range of electrochemical instrumentation. Products include potentiostats and
electrochemical software for electrochemical research, battery testing, fuel
cell development and corrosion science. Gamry electrochemical instruments
perform physical electrochemistry, pulse voltammetry, cyclic voltammetry (CV),
electrochemical impedance spectroscopy (EIS), dc corrosion measurements, and
electrochemical noise.
POTENTIOSTATS
Gamry designs and manufactures the Reference™ 600,
Reference 3000, Series G™ 300, and the Series G™ 750 Potentiostats.
To a large extent, you choose a potentiostat based on the current level
expected in your experiments. Gamry Potentiostats can function as a
potentiostat, a galvanostat, or a Zero Resistance Ammeter (ZRA). They utilize
on-board circuitry to perform electrochemical impedance spectroscopy (EIS).
Both current-interrupt and positive feedback iR compensation are standard.
Gamry Potentiostats electrically float, allowing electrochemical experiments
with grounded samples.
COMPUTER
Gamry Potentiostats interface to a Windows-compatible
computer through either a USB port or PCI slots. Gamry can provide either a
desktop or a notebook computer for your application, or you may purchase your
computer independently.
SOFTWARE
Gamry offers a complete library of electrochemical
application software for Windows. Electrochemical experiments are performed in
the Gamry Framework™ and the data is analyzed in the Gamry Echem
Analyst™. Since all experiments have the same look-and-feel, learning a
new application is easy! Custom experiments can be accomplished with Open
Source Scripting.
PHE200™ Physical Electrochemistry
Software
The PHE200 provides a complete library of
electrochemical techniques for characterizing electrochemical reaction
mechanisms and studying the electrode interface:
- Cyclic Voltammetry
- Chronoamperometry
- Chronopotentiometry
- Chronocoulometry
- Controlled Potential Coulometry
- Linear Sweep Voltammetry
PV220™ Pulse Voltammetry Software
The PV220 Software is a companion to the PHE200. The
extraordinary sensitivity of the pulse techniques allows electrochemical
measurements to be made at very low concentrations. The PV220 includes the
following techniques:
- Square Wave Voltammetry
- Differential Pulse Voltammetry
- Normal Pulse Voltammetry
- Reverse Normal Pulse Voltammetry
- Sampled DC Voltammetry
- Generic Pulse
EIS300™ Electrochemical Impedance Spectroscopy
Software
EIS is a powerful tool for a wide range of applications.
Using the unique Sub- Harmonic Sampling, Gamry has civilized EIS - it's
accurate, it's easy to use, and it's affordable. With a frequency range from 10
?Hz to 1 MHz and an impedance range from m? to T? (that's 1012 ohms!), the
EIS300 exhibits outstanding performance. Gamry offers the widest range of EIS
techniques, including potentiostatic, galvanostatic, and hybrid (great for
batteries and fuel cells). The EIS300 works nicely with the ECM8™
Multiplexer for automated measurements of multiple samples. The EIS300 includes
a powerful modeling program to interpret your EIS data. Build your model with a
click-and-drag Model Editor. Fit the data to the model using either a
Levenberg-Marquardt or a Simplex algorithm.
DC105™ DC Corrosion Techniques Software
The DC105 software includes 14 electrochemical
techniques for the study of corrosion. Corrosion rates can be measured using
Polarization Resistance or Tafel Plots. Potentiodynamic Plots, Cyclic
Polarization, and Critical Pitting Potential are available to evaluate
passivity and pitting. Using the ECM8 Multiplexer, up to eight samples can be
measured automatically by the DC105. Thanks to the floating design of Gamry
Potentiostats, you can take them to the field with a notebook computer and
perform measurements on pipelines and vessels.
