The Fraunhofer Institute for Process Engineering and Packaging IVV and Presens Precision Sensing have engaged in a joint project resulting in a prototype device for trace oxygen measurement. It is easy-to-handle and cost-effective. The detection limit of 0.5 ppm in the gas phase of the new, highly sensitive sensor TAF12 allows measurements lower by a factor of 50 than in systems used so far and has a dynamic range of 0 – 1000 ppm (gas phase).
The newly designed measurement cells with improved leak tightness are made of stainless steel. The new measurement system together with the TAF12 sensor by Presens is an easy-to-use and cost-effective method to determine oxygen permeability of important synthetic materials. Serial production is planned soon.
