Potential ±10 V Compliance Voltage ±14 V (±120 V boosted) Frequency Range 10 µHz to 3 MHz Zahner M e s s s y s t e m ® e Electrochemical Workstation 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 • • • • ultra low-noise potentiostat wide frequency range DSS FRA high CMRR precision U/I-amplifiers high resolution differential ADCs 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 HIZprobe 3% / 5o dard applications. Furthermore, it can be extended with additional IM6ex 2% / 3o hardware and software. This 9 makes it easy to adapt it to a lot of very different applications from the 6 high-impedance end (corrosion, laminates, coatings, etc.) to lowIM6ex 0.5% / 0.5o 3 impedance objects (batteries, fuel cells, etc.). If in the course of an investigation it turns out that addi0 tional methods are needed, it is no problem to fit the IM6eX to that -3 galvanostatic 2% / 3o new situation. For this purpose the IM6eX provides four slots for plug & play extension cards. Thus, you -4 -2 0 2 4 6 8 log f 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. log /Z / 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.

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. RV Noise CIMPS CIMPS 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).
