- Quartz crystal microbalance - Wikipedia
A quartz crystal microbalance (QCM), also known as quartz microbalance (QMB) and sometimes also as quartz crystal nanobalance (QCN), measures a mass variation per unit area by measuring the change in frequency of a quartz crystal resonator
- Quartz Crystal Microbalance (QCM) | Nanoscience Instruments
What is Quartz Crystal Microbalance (QCM)? Molecular adsorption via the vacuum or gas phase typically results in rigid films that are fully coupled to the oscillation of the electrode surface
- Quartz Crystal Microbalance - QCM200
The QCM200 Quartz Crystal Microbalance measures mass and viscosity in processes occurring at or near surfaces, or within thin films This system includes a controller, crystal oscillator electronics, crystal holder, three quartz crystals, and Windows software
- The utilization and advancement of quartz crystal Microbalance (QCM): A . . .
Quartz crystal microbalance (QCM), being a mass-sensitive sensor, has the benefit of achieving high accuracy (up to nanogram level), providing real-time digital frequency output, and being easy to operate
- What is Quartz Crystal Microbalance (QCM) technology? An Introduction
Quartz crystal is a piezoelectric material that generates an electric charge in response to mechanical stress, and vice versa QCM technology utilizes this property to precisely measure small changes in mass or thickness of layers adhering to the surface of a quartz crystal
- The Principles of QCM-I - QCM Sensors
In QCM-I, the impedance of the quartz crystal sensor is measured using a network analyzer to accurately determine the frequency and bandwidth of the crystal resonance This is done over multiple frequency ranges to measure the fundamental and overtone resonances

The Quartz Crystal Microbalance with dissipation monitoring (QCM-D) is a tool to measure mass and viscosity in processes occurring at or near surfaces, or within thin films
- The working principles of QCM and QCM-D technology - Biolin Scientific
In summary, the QCM, which is a real-time, surface sensitive technique, monitors the change in mass or thickness of layers adhering to the surface of a quartz crystal This is achieved by measuring the change in resonance frequency of the quartz crystal upon excitation by a driving voltage, Fig 2
