Abstract :
QCR (quartz crystal resonator) sensors afford the visualization and continuative research of chemical, biochemical or microreactor processes. In this context, the resonant frequency and the attenuation of the sensor are important parameters. The paper discusses a new concept for measuring both parameters within very short cycle times which allow the tracking of fast dynamic processes during those reactions.
