Q-Sense Omega Auto QCM-D surface analysis system

The Q-Sense Omega Auto surface analysis system is an intuitive instrument and software platform that senses mass change, layer thickness, binding and molecular orientation at the nanoscale. The principle is that of quartz crystal microbalance with dissipation (QCM-D).

Requiring only 30 μL of sample per sensor, the eight sensor module enables high throughput and good reproducibility. Temperatures can be set between 4 and 70°C, enabling stable temperature control.

Applications include protein conformational changes, lipids, surfactants, nanoparticles, polymers and whole cells. It is possible to determine the water content of molecular layers and calculate film viscosity, elasticity, mass, thickness, density, affinity and specificity. Interactions can be studied on many substrates such as gold, metals, polymers and functionalised coatings.
