Quartz Crystal Microbalance, open-source QCM device for accurate mass sensing and analysis in research, industry, and education.

A quartz crystal microbalance (QCM) (also known as quartz microbalance (QMB), 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.

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.

openQCM is a scientific as much as a smart device based on the quartz crystal microbalance technology. A quartz crystal microbalance (QCM) is a surface sensitive technology capable of measuring phenomena at molecular scale.

2019年4月6日 · The QCM-I uses a network analyzer to measure the complex impedance of the sensor over a range of frequencies around each resonance selected. The software then fits these curves to accurately determine the frequency of the conductance maximum (the resonance frequency, f r ) and the bandwidth of the peak (Full Width at Half Maximum, FWHM), both ...
