Abstract

Oxygen solid electrolyte coulometry (OSEC) based on electrochemical cells made of yttria-stabilized zirconia (YSZ) is a long-standing method for gas sensing, material characterization as well as biological or medical measurements of oxygen exchange. Newer approaches are directed on analytical applications for chromatography or dissolved gas measurements. With optimized cell construction and operating conditions, the method enables the detection of gaseous quantities down to the picomolar range. The contribution gives an overview on the most important parameters, the characteristics and requirements regarding the sensors and also on actual developments.
