You have a special project in mind with a new experimental concept and need a customized experimental set-up? You want to measure several samples in parallel? You have problems with degradation of your samples? Tell us what kind of customized equipment you need. We have years of expertise in building specialized experimental equipment for fundamental research in the fields of electrochemistry and Solid State Ionics. This knowledge we want to use to build sustainable, functional and easy usable test stations for you. In the following sections, you find some examples for customized equipment built by Huber Scientific.
A in situ sample stage to investigate thin film Solid State Devices at elevated temperatures (RT to +1000 °C) in gas atmosphere. The sample holder is equipped with a transfer mechanism for a thermocouple type S and a 3-electrode terminal for reference electrode measurements using the novel “Wing Geometry”.
This set-up has five individual spring mounted needles to contact five micro devices on one sample. It is possible to polarize an electrochemical cell and measure the sheet resistance with Van-der Pauw while performing beam line experiments. This versatile sample holder is designed for various applications in the fields of electrochemistry and Solid State Ionics. It can be used in cryogenic measurements up to 120 °C but and can be adapted to high temperature measurements.
Combine in situ optical measurements with electrical and gas exchange measurements at elevated temperatures. This setup can work in reflective and transmission mode and can measure samples with a maximal diameter of 20 mm.
THREE- AND FOUR-POINT REFERENCE ELECTRODE TEST STATION
There are two common methods to measure the impedance response of only one electrode of a solid-state electrochemical cell; microelectrodes or a three-terminal configuration. In aqueous electrochemistry, three-terminal configurations are widely used, however, implementing this method in solid-state electrochemistry is highly non-trivial. Three important error sources are present in non aquarius systems: - Asymmetric sample cells - Short circuit currents across the reference electrode (RE) - Especially for highly resistive electrodes, coupling capacitances between the three electrodes. These error sources can result in different measurement errors such as additional high frequency semicircles, additional low frequency semicircles, inductive loops and even more critical, erroneous electrode properties without indicating of additional features in the impedance spectrum. This test station in combination with the novel sample geometry, called wing geometry, minimizes measurement errors and provides a tool for reference electrode measurements for a wide range of applications.
Tracer exchange experiments can be a powerful tool to study diffusion properties , surface exchange reactions , visualize reaction sites , identify grain boundaries and other defects , identify different reaction pathways  or use it to post analyses diffusion properties of other operando experiment .
Tracer exchange experiments are not limited to gaseous oxygen tracer exchanges. There are several other methods available as well: E.G. Tracer marked water , hydrogen  or solid tracers for cation diffusion .
We already developed vacuum chambers for:
Voltage driven exchanges
Short time exchanges including fast heating and quenching inside the chamber
