GENERAL INFORMATIONS

Elettra is an highly accurate quartz crystal microbalance system developed for piezoelectric gravimetry in the ng-pg regions, it has been designed to work both as QCM for stand alone operation and as EQCM (Electrochemical Quartz Crystal Microbalance) when used with a Potentiostat.

If used in conjunction with a potentiostat / galvanostat, actually the Elettra crystal holder is designed so that only the front crystal electrode is exposed to the liquid under test, this electrode can be used as a Working electrode by a potentiostat as required in EQCM experiments, this feature combined with an analog output, proportional to the Df change, makes Elettra compatible with virtually all potentiostats.

When used as EQCM Elettra allow us to undergoing charge transfer reactions in the redox equilibration process. Quartz crystals can be pre-coated with any thin film material like organic polymers, ceramics, living cells and bacteria, biomaterials and hydrogels performing a real time mass measurement in process occurring at or near crystal quartz surface or within the thin film.

For all these reasons Elettra is a valuable research tool for many applications ranging from electrochemistry to pure surface science, measuring very small mass changes in both liquid and gas phase environments, this provides an unlimited potential for the novel gas and biological sensors development.

DESCRIPTION

Elettra is an extremely easy to use instrument, having only four push buttons, one used to clear the Df value while the others allow to choose what data to show over the eight digit display:

the "ZERO"push button clears the Df value saving the quartz resonant frequency before the beginning of the experiment

the "F"push button displays the instantaneous frequency acquired over the display

the "F0"push button displays the resonant frequency saved with the "ZERO"push button

the "F-F0"push button displays the instantaneous Df acquired during the experiment
