Within our lab, we have several set-ups in which we can mix up to 9 gasses simultaneously, control temperature, and humidify gas streams. These set-ups are used to test materials under different gas atmospheres as well as optical (fibre) hydrogen sensors. We use it to discover new materials and to test whether the materials and sensors are cross-sensitive to other conditions or whether other adverse effects happen.
