Quartz Crystal Microbalance


Small and mighty

The BluQCM QSD is a single channel, compact and modular instrument. Its low footprint and lightweight makes it particularly suitable for crowded labs. It is available as standalone, with temperature control or/and flow control.

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.



AWS Suite® is the software controlling the BluQCM products.

It enables the user to manage the entire experiment. One interface manages both the acoustic and electrochemical interface, and can provide flow management as well if needed. Moreover, an analysis package is also available to process the data on-line.
