The Quartz Crystal Microbalance provides mass and structural information on molecular layers that form on the surface of a sensor. Molecular adsorption and interactions can be monitored in real time under a variety of conditions.  Sensors can be chemically modified to produce a range of surfaces for study.


QCM can be used in a range of applications, for example  to investigate the hydration of polymer films, monitor protein interactions with a variety of surfaces, or study the effectiveness of surfactants in removing lipid films.
            •  Multiple sensor unit for up to four flow cells in series or parallel configuration
            •  Electrochemical cell
            •  Temperature range from 15 – 45 °C
            •  Dissipation monitoring gives information on rigidity of film
            •  Sensitivity of the order of 2 ng cm-2
            •  Resolution of 200 data points per second
