Impedance measurement system
Impedance measurement system

Samples are placed between two spring-loaded Pt wire meshes inside a home-built measuring cell made out of boron nitride. The cell can be heated by a small computer-controlled furnace up to T > 1000?C in inert and oxidizing gas atmospheres. The current setup measures the impedance without any standards and accurate values at high frequencies can not be expected.

Capabilities/Accessories

The measurements are controlled via a program Smart (Solartron Materials Research and Test software, version 2.8.0). In addition there are two free programs for data inspection and simpler equivalent circuit analysis: Zview2 and Zplot. There are no extra coaxial cables or reference impedances.  The system is sufficiently automatic for a heating-cooling temperature scan to be made for one sample per day.
