Investigation of mass changes by piezoelectric resonator
Kužílek, Jakub ; Svoboda, Vít (referee) ; Špičák, Petr (advisor)
An operation deals with a concept of the new cell for measuring weight changes with high precision through the use of quartz crystal micro-scales called QCM. The new cell is destined for crystal resonators which diameter is 14mm. The resonators are produced in the Czech Republic. A price is the greatest advantage of crystal resonators in comparison with original crystals. The next positive is higher mechanical tolerance which is outgoing of a guest-size. The cell designed by this way is tested in electrochemical system where a deposition of metallic copper in crystal is happening. A homologation of accuracy is judged by Faraday’s law and using Sauerbrey equation for quartz crystal microbalance in cyclic voltammetry measurement method.
