TRACER EXCHANGE SET-UP

Tracer exchange experiments can be a powerful tool to study diffusion properties [7][8], surface exchange reactions [9], visualize reaction sites [10], identify grain boundaries and other defects [11][12], identify different reaction pathways [13] or use it to post analyses diffusion properties of other operando experiment [14].

Tracer exchange experiments are not limited to gaseous oxygen tracer exchanges. There are several other methods available as well: E.G. Tracer marked water [5], hydrogen [16] or solid tracers for cation diffusion [17].

We already developed vacuum chambers for:

  • Thermal exchanges
  • Voltage driven exchanges
  • Short time exchanges including fast heating and quenching inside the chamber

IN SITU OPTICAL TEST STATION

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.

MULTI SAMPLE TEST STATION

Measure up to four samples in four wire mode in parallel in the same atmosphere and at the same temperature.
