Quartz Crystal Microbalance with Dissipation (QCM-D)

Overview

QCM DThe Q-Sense Quartz Crystal Microbalance with Dissipation (QCM-D; E4 Auto) monitors molecule-surface interactions, thin film formation and layer properties.

QCM monitors mass changes at the sensor surface with nanoscale resolution via frequency measurements, and monitors energy loss (i.e. dissipation) to characterize structural or film changes.

It is commonly used to characterize binding and the formation of thin films.

This system can capture the kinetics of both structural changes and mass changes simultaneously.

This instrument is wide used with our Spin Coater – the Spin Coater is used to prepare the sensors.
