BluQCM QSD

A new, high-end, single-channel, Quartz Crystal Microbalance

An instrument capable of measuring highly accurate changes in the mass of thin rigid layers as well as determining the properties of visco-elastic films.

The flexibility of the BluQCM QSD is relevant to both electrochemically-driven mass-weighing applications (electroplating/corrosion, electrode modifications) and the more advanced
studies of solid/liquid interfaces (interface rheology, biomolecular interactions).
Simultaneous measurements can be performed of up to 7 overtones (fundamental included) enabling a complete determination of the layers’ properties. Measurements in air, gas, and liquid are possible.
A fast acquisition rate increases mass sensitivity. And patented quick-lock sensor cells facilitate set-ups as well as increase the reproducibility of experiments.
All that, and you can control all coupled instruments, including potentiostat/galvanostats, with the same software for eQCM experiments.
