PEM sample holder
The newly designed PEM sample holder is a small, compact unit for 4-electrode conductivity measurements of self-standing polymer film slabs (e.g. PEM). The sample holder is designed for and will fit any ProboStat™ unit. Temperature range from RT to ›200°C. A heated ProboStat™ base unit allows high steam contents if desired. In combination with the HumiStat tailor-made gas mixer and humidifier, this forms a high throughput measurement system for PEM conductivity at high temperatures and controlled partial pressures of water vapour.
Together, the HumiStat and the heated ProboStat™ base unit with sample holder for small PEM slabs, offers a simple and price-economic alternative to larger PEM characterization systems on the market.
A standard potentiostat with impedance spectrometer (frequency response analyzer, FRA) will be suitable for most samples and measurements.MORE
