EMF transport number measurements
In the ProboStat sample holder a disk sample can be suspended with suitable sealing material to form two separate gas chambers and each chamber supplied with desired gas mixture.
Using top and bottom (and maybe guard) electrodes the user then performs measurements with desired gradients over the sample. The voltage is measured by a high-impedance voltmeter, and is a measure of ionic transport numbers in the sample.
Measurements of total conductivity are easily performed during the EMF-measurements by manual switching or automatic multiplexing of the electrodes, and the combination of these two methods is a powerful tool in the investigation of the electrical conductivity of a material.
