Features of Quartz Crystal Microbalance

qCell T by 3T Analytik

qCell T comprises a small volume flow cell on a high precision and powerful Peltier driven temperature (T) control system for cooling and heating, a thermostated sample holder and an attached pump for liquid handling.

qCell is an entry-level version with identical features without T control and no integrated pump control. Sensor data acquisition, thermal control and fully automated pump operation are all carried out under the common uder interface of the qGraph software.

QCM Principle and Measurement

Quartz sensors are highly sensitive to the mass and the material properties of deposited molecular layers as well as of the wetting liquids at their surface. Due to its sensitivity to mass, the technique is often referred to as Quartz Crystal Microbalance (QCM). 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.
