IM6eX
The Electrochemical Workstation IM6eX is the latest member of the famous IM family. It was developed using our 25 years of experience in producing high-precision electrochemical workstations of
the high-end class. Based on the IM6e, it provides extended features such as a wider frequency
range, higher output current, additional extension slots and an USB interface. Special measurement
techniques guarantee an ultra high accuracy and a minimal interference with the test object.
The IM6eX comes bundled with the outstanding Thales software package which offers all standard
methods and more at a mouse click. This is why the IM6eX can easily be adapted to very different
measurement requirements. Furthermore, with the manifold options available, the IM6eX is able to
grow with its tasks. Thus, it is best suited for investigations on fuel cells and batteries as well as on
membranes and sensors or on coatings and laminates – to name only some.
Last but not least, Zahner is known to provide the most competent service all around the world. Our
25-years experience does not only cover the electronics but also the electrochemical part with its
partially complex applications.
The hardware of the IM6eX is based on the popular IM6e model. It provides

All these components are designed to work together in a perfect way. This results in a homogeneous and compact instrument with extraordinary technical data.
The accuracy map of the IM6eX clearly shows the high quality of the hardware.
The IM6eX is a highly versatile
instrument providing a lot of stan12

may have up to e.g. 16 external
potentiostats connected to the IM6eX. No matter if you decide to record additional channels
(temperature, pH, etc.) or if you need higher currents or you have to investigate electrochemical
noise or … or … - simply plug in the appropriate card, connect the test object, and start working.
The Thales software supports all options automatically and provides the methods needed.

The highest priorities for the development and production of the IM6eX instruments are accuracy
and reliability. For that reason we do not waste paper with senseless specifications like a “virtual”
resolution calculated from the resolution of the AD converter. The resolution and accuracy we
specify are real ones relevant to the use in practice, based on the high-end hardware we use.

The Thales package supplied
with the IM6eX is one of the most
sophisticated software packages
for electrochemical applications.
On the one hand it provides a
huge variety of methods, on the
other hand it is easy to use even
for not trained personnel. Help
pages are popping up on a
mouse click showing hints for
most of the functions.

SCRIPT
-
With SIM, the user is able to
design equivalent networks on
the screen and fit them to the
measured data. Especially this
part of the Thales software is one
of the most sophisticated one in
the market today. Besides a big
library of all electrochemical standard elements you can easily add
user-defined elements. More
highlights are the automatic finding of starting values for the network elements and the versatile
processing of time dependent
effects.
SCRIPT allows you to program
your individual procedures easily,
so that even complex measurement- analysis- and documentation tasks will run automatically.
There are some ready-to-use
SCRIPTs available from Zahner,
such as COLT or CIMPS.
Many electrochemical standard
methods are available in the
Thales package and can be used
without
additional
hardware.
Some others are implemented in
Thales but need additional hardware (see table to the left). External potentiostats are connected to
the IM6eX through EPC40 cards,
each of which controls up to 4
pots (up to 16 pots in total).
The IM6eX can be controlled
from external software (e.g.
LabView®). The same way,
Thales is able to control external
instruments through the NET
software interface (TCP/IP).
