Short summary
Because of their direct impact on patients, medical supply lines are under strict regulations and have to be monitored in terms of purity on a regular basis. State-of-the-art measurement solutions do not allow for continuous bedside monitoring. The aim of the presented work is to provide a compact multispecies monitoring system based on the latest quantum cascade laser technologies allowing for the continuous bedside monitoring of medical gases.
