QCM-I Quartz Crystal Microbalance is a high-sensitivity mass sensor which measures the change in frequency and dissipation of a quartz crystal resonator and any adsorbed film.
QCM-I Features:
- Both the frequency and the quality of resonance (FWHM or bandwidth or dissipation) are measured
- Different harmonics (up to the 13th overtone at 5MHz crystals) can be quickly and sequentially measured
- Temperature control from 4°C to 80°C (± 0,02 °C) is included
- EC measurement module is optionally available with ITO-QCM sensors
- Modular sensor holder up to 4 measuring channels
- External PC with Windows® 10; communication with QCM-I via USB
Measuring thick coconut oil films and cleanup using QCM-I
This application note describes the data obtained from films of Virgin Cold-Pressed Coconut Oil spin coated onto a MicroVacuum Au coated QCM-I sensor crystal. The QCM-I instrument monitors the impedance spectrum of an oscillating quartz crystal sensor, tracking the changes in the resonant frequency (F0) of its fundamental and overtones as well as their peak widths (Full Width Half Maximum, FWHM), all in Hz.
Fluidic configurations for QCM-I
This technical note summarizes the basic fluidic configurations that can be used with the QCM-I flow-cell sensor holders which are part of both QCM-I systems. The pump and injection valve options are provided as part of the QCM-I configuration and can be added to the QCM-I Mini base specification.
Measurement of protein and nano-particle adsorption using QCM-I
Quartz crystal microbalance with impedance (QCM-I) is a powerful technique for measuring the adsorption or binding of polymers, proteins, nano-particles, and other molecules to a surface. In this application note from Gamry Instruments, discover how to obtain real-time, multi-parametric measurements of protein and nanoparticle adsorption.
The principles of QCM-I
In this application note, Gamry Instruments presents the Quartz Crystal Microbalance with Impedance Analysis. The Quartz Crystal Microbalance is a well-established and sensitive technique used to measure the interactions of molecules, polymers and biological assemblies with a sensor surface, in air or liquid, label-free and in real time.
