8. Q-Sense E4 Quartz Crystal Microbalance (QCM-D)

The Q-Sense E4 QCM with dissipation is a real-time analytical instrument for studies of molecular events occurring on surfaces. The E4 measures mass and viscoelastic properties of molecular layers as they build up or change on the sensor surface. Areas of interest include materials, protein and surfactant research.
