AWS X1

 

The acoustic sensing principle is based on the precise detection of changes on the properties of an acoustic (mechanical) wave traveling through the bulk or the surface of the acoustic wave sensor.

 

The X1 system allow a real-time and sensitive monitoring of surface-bound interactions, such as adsorption and desorption processes, characterization of molecular interactions, protein conformational changes and electrochemically-driven mass changes. The QCMD technology is based on the acoustic wave sensing principle, which enables an accurate detection of mass and structural changes on the sensor surface via dissipation measurements. The system can be coupled to a BioLogic potentiostat/galvanostat to perform electrochemical QCM measurements in the same software. The platform is versatile, allowing the use of different types of acoustic wave sensors, including up to 150 MHz High Fundamental Frequency (HFF) sensors and 5 MHz to 10 MHz sensors. The platform can also include high accuracy temperature and flow control for applications sensitive to temperature and requiring the renewal of liquid medium.
This instrument allow dissipation determination and measurements at multiple overtones for a comprehensive description of the properties of the surface.
