Instruments for electrochemical research

Dedicated to research

2
Metrohm Autolab sets the standard for electrochemistry instrumentation. Over 30 years ago, we created the
first commercially available digital potentiostat/galvanostat that was completely computer controlled. Today our
NOVA software is the most powerful electrochemistry software on the market.

Metrohm Autolab creates instruments that are suitable for most application areas including: corrosion, energy,
environmental, sensors, and solar. Our customers may not always be electrochemists, but they are engaged in
fundamental and applied research harnessing the power of electrochemistry for further understanding. They
are driven to understand and improve electrochemical processes with the ambition to deliver new materials with
superior properties and future possibilities.

With an Autolab potentiostat/galvanostat and NOVA software there are no limits to where your research can go.

Metrohm Autolab Modules

Electrochemical With the FRA32M module you can use EIS to quantify all elements of your
impedance electrochemical system. The module gives you a wide frequency range (10 μHz to
spectroscopy 1 MHz) and with the NOVA software you can have complete data analysis (fit and
module (FRA32M) simulation) available within a click. The module also maximizes the resolution
of measurements with the Automatic Amplitude Correction algorithm (AAC)
providing accurate impedance measurements.

High frequency The ECI10M is ideal for solid state electrochemistry with expanded
impedance measureable range for EIS to a maximum of 10 MHz and ultra-fast reaction
spectroscopy mechanism for greater insight into the electrochemical interface. With a small
(ECI10M) form factor it is suitable for your lab bench, Faraday cage or glovebox.

True analog scan A true analog scan generator module is exactly what it sounds like -
generator module up to 250kV/s† allows you to measure fast reaction rates, reaction
(SCAN 250) kinetics, reversibility of electrochemical processes.

Dual-channel ultra- The Autolab ADC10M captures ultra-fast surface reactions by increasing the
fast sampling sample rate down to a 100 ns interval for 2 signals.
module (ADC10M)

Dual-mode With the Autolab Dual-mode bipotentiostat module (BA) you can design
bipotentiostat experiments that use 2 independently controlled working electrodes in the
module (BA) same electrochemical cell. Using either fixed potential or the scanning mode you
can expand your exploration in a convienient setup.

Booster 10A/20A Give your current a boost with the Autolab Booster expanding your
application options including electrochemical impedance (EIS) measurements
when used with a FRA32M. The fast response time coupled with four
quadrant operation* will give you detailed data that you can analyze for
greater insight in to your experiment.

Metrohm Autolab Modules

Low current Increase data accuracy by vastly decreasing the minimum measurable current of
amplifier module your experiment with the Autolab ECD. With a built-in amplifier you can measure
(ECD) current peaks down to a few picoAmps which opens new possibilities in sensor,
corrosion and other research applications.

Electrochemical An additional hyphenated measurement is possible with the Autolab EQCM by

Quartz Crystal recording the change of the resonant frequency of a quartz crystal oscillator and
Microbalance measuring the mass change per unit area.
Module (EQCM)

Multiplexer The Autolab Muliplexer module allows you to increase throughput with
module (MUX) automated sequential measurements in the configuration of your choosing. Your
setup can be comprised of electrochemical cells, voltage measurements, or
working electrodes. There is a manual option for additional testing.

Analog filter and With the Autolab FI20 the analog filter gives you the ability to remove
integrator module external noise and interference from the measured signal. You can smooth
(FI20) your data using up to 3 different time constants giving you more accuracy
and greater confidence in your results.

The integrator in the Autolab FI20 combines time and current for conversion
to Coulombs which you can monitor in real-time for experiment versatility.

Voltage and pH The pX1000 module provides simultaneous and highly accurate pH,
measurement additional voltage and temperature measurements. A variety of experiment
module (pX1000) configurations are possible with this module and you can even set your own safety
cutoffs depending on your experiment requirements.

Electrochemical The ultra-sensitive Autolab ECN allows in-depth understanding of localized

Noise Module corrosion. This is possible by measuring, in-situ, difficult to detect stochastic
(ECN) electrochemical noise as a function of time. NOVA provides seamless analysis of
the measured noise at open circuit.
