quartz crystal microbalance

Most such instruments use a quartz crystal microbalance as the sensor.

This is a specialised application of the Quartz crystal microbalance as a biosensor.

A quartz crystal microbalance is capable of measuring mass deposition down to 0.1 nanograms.

His method continues to be used as the primary tool in quartz crystal microbalance experiments for conversion of frequency to mass.

The quartz crystal microbalance provides just such a tool having a resonant frequency of about 10 kHz.

According to Okahata and his colleagues, the lipid-coated quartz crystal microbalance is both physically stable and reusable.

Quartz crystal microbalance is a very sensitive mass deposition sensor based on the piezoelectric properties of the quartz crystal.

Another example of a physical probe is the use of the quartz crystal microbalance (QCM) to study binding kinetics at the bilayer surface.

An alternative is to use surface sensitive techniques to follow particle deposition, such as reflectivity, ellipsometry, surface plasmon resonance, or quartz crystal microbalance.

A different process using a quartz crystal microbalance has been devised for measuring smaller samples on the order of a microgram (versus milligram with conventional TGA).

A quartz crystal microbalance (QCM) measures a mass per unit area by measuring the change in frequency of a quartz crystal resonator.

Biochemical Detection is the science and technology of detecting biochemicals and their concentration where trace analysis is concerned this is usually done by using a Quartz Crystal Microbalance.

The Quartz Crystal Microbalance with Dissipation Monitoring (QCM-D) is a special type of QCM based on the ring-down technique.

QCM (Quartz Crystal Microbalance) - to test whether a Japanese-manufactured quartz microbalance works well in monitoring contamination of the satellite from assembly to on-orbit operation.

Additionally, in recent years the Michell group has developed quartz crystal microbalance technology for trace moisture measurement in gases as well as thermo-paramagnetic and zirconium oxide oxygen sensors and analysers.

Yoshio Okahata and his colleagues, at the Tokyo Institute of Technology, have built an ingenious piece of equipment, based on a quartz crystal microbalance, which can weigh nanogram quantities of lipids.

The resonant frequency of a quartz crystal oscillator is changed by mechanically loading it, and this principle is used for very accurate measurements of very small mass changes in the quartz crystal microbalance and in thin-film thickness monitors.
