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.
What is Quartz Crystal Microbalance (QCM) Technology? Quartz Crystal Microbalance with Dissipation Monitoring (QCM-D) is a powerful analytical technique used to study nanoscale surface interactions in real-time and label-free.
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.
QCM Research specializes in the design and manufacture of very high quality Quartz Crystal Microbalances, known as QCMs.
The QCM is an acoustic technology, i.e. it measures changes of sound. The sound is typically in the MHz regime, however, and not detectable by the human ear. The core of the technology is the oscillating unit - a thin quartz crystal disk, which has electrodes deposited on each side.
Quartz Crystal Microbalance, open-source QCM device for accurate mass sensing and analysis in research, industry, and education.
The quartz crystal microbalance is an essential addition to any biological laboratory. The data from a QCM perfectly complements that obtained from other techniques, such as surface plasmon resonance (SPR) and atomic force microscopy (AFM), aiding in the analysis of complex biological interactions.
Quartz Crystal Microbalance (QCM) is an instrument that allows a user to monitor small mass changes on the surface of a coated quartz crystal.
The QCM is a versatile tool that can quantify the mechanical properties of thin-film polymer glasses, gels, and complexes in both air and liquid environments as a function of external conditions, such as changing temperature or pH/ionic strength.
