Gravimetric tools : operation, possibilities and applications


Gravimetric sensors are inexpensive devices which, in a first approach, allow the measurement of mass variations in the range of ten nanograms performed in air or in contact with a liquid. In general, they are referred to quartz crystal microbalances (QCM) and operate according to chronometric principles based on piezoelectric quartz resonators. An oscillator is used to recover the resonance frequency, which is itself related to variations in mass of a certain film deposited on the QCM: a linear relationship, known as Sauerbrey equation, is established between these variations in frequency and mass. However, different conditions must be respected in order to use this equation because the devices are sensitive to other quantities such as the roughness/mechanics of the films studied, and the characteristics of the electrolyte in contact with these films. In terms of gravimetric sensitivities, typically it is possible to measure mass variations of a few nanograms for resonance frequencies of around a few MHz. Different applications are possible with these gravimetric sensors and the main domains which can be explored are in health [1,2], environment [3,4] or energy [5,6] from both a fundamental and an applied point of view.
