Zur Volumenstromanalytik bei Gasphasenreaktionen mit veränderlicher Molzahl

Two methods of measuring the volumetric throughput of gas phase reactions with changing total mole number are compared. The first method determines the time which an injected impulse of an other gas needs to pass a calibrated volume. In the second method the concentration change of an inert gas due to reaction is measured. Both methods gave comparable results but the standard deviation of the second method was about four times larger. The influence of the introduction of an inert gas on reaction kinetics is discussed
