What is QCM used for?
QCM at a glance A quartz crystal microbalance (QCM) is an instrument that monitors very small changes in mass (fractions of monolayers etc.) and viscosity with respect to the presence or state of a given system in real-time.

What is QCM biosensor?
The quartz crystal microbalance (QCM) is a biosensor platform that incorporates a mechanical transducer, which operates on the principle of mass detection.
How much does a QCM cost?
I’ve checked a few sources for the price of a QCM and they come in a range of about USD 4000 to 5000.
How does quartz crystal work as a sensor?
6.10 Mass Sensors. QMC is based on sensing changes in acoustic resonant frequency of a quartz crystal caused by the binding of an analyte on its surface. Here, an external oscillating electric potential is applied across the crystal that induces an acoustic wave through the piezoelectric effect that resonates.
What is quartz measurement?
The quart (symbol: qt) is an English unit of volume equal to a quarter gallon. Three kinds of quarts are currently used: the liquid quart and dry quart of the US customary system and the imperial quart of the British imperial system. All are roughly equal to one liter.
Is a quartz crystal that oscillates at a well defined frequency?
As a result, quartz crystals make an excellent component choice for use in oscillators especially very high frequency oscillators. Typical crystal oscillators can range in oscillation frequencies from about 40kHz to well over 100MHz depending upon their circuit configuration and the amplifying device used.
Who invented QCM?
Günter Hans Sauerbrey
Unsourced material may be challenged and removed. Günter Hans Sauerbrey (1 January 1933 – 15 May 2003) was a German physicist who invented the quartz crystal microbalance (QCM).
Why quartz crystal is used?
Quartz crystals maintain a precise frequency standard, which helps to regulate the movement of a watch or clock, thus making the timepieces very accurate. Quartz is also used in radios, microprocessors, and many other technological and industrial applications.
