Q-Sense analysis systems for measurement of surface-molecule interactions

Click2Contact

Q-Sense offers a series of analysis systems designed to measure surface-molecule interactions in real time using quartz crystal microbalance with dissipation (QCM-D) monitoring technology.

The launch of the Q-Sense Initiator has enabled surface scientists, who have a need for an introductory Q-Sense system capable of fundamental analysis, to gain access to the technology. Q-Sense Initiator maintains the core Q-Sense functions and quality while focusing on more customer segments. The Q-Sense Dfind software simplifies data handling and reporting through an intuitive interface and powerful tools for complex analysis.

QCM-D monitoring (patented by Q-Sense) enables real-time measurements of both mass/thickness (frequency) and structural properties (dissipation) of molecular layers. By measuring the dissipation parameter (D), the QCM-D allows for the analysis of soft films that do not obey the linear relation between change in frequency and change in mass. In this way the dissipation parameter provides novel insights regarding structural (viscoelastic) properties of adsorbed layers. Combined with the Q-Sense Dfind analysis software, the user can access information such as mass, thickness, viscoelastic properties and adsorption rates, and quantify, compile and compare data from start to end.
