What is QCM-D

Principle of QCM-D

The measuring principle of quartz sensor technique is based on the precise oscillation of the quartz sensors at their resonant frequency when an alternating voltage is applied. Depositions at the sur­face or wetting of the surface result in a frequency shift and – depending on the material properties – additionally in a damping of the oscillation. Both, the frequency shift and the damping (dissipation) of the oscillation are cap­tured with the qCell / qCell T instrument with high resolu­tion and in real time.
