ToF-SIMS imaging of a diagnostic microarray surface.

Part of the mass spectrum recorded with a sub-monolayer antibacterial coating.

A high-sensitivity platform with sub-micron spatial resolution for characterising the surface chemistry of samples from the environmental, physical and life sciences.

Benefits :

• Mass spectra of surface layers of materials and absorbed molecules.
• Imaging of spatial distributions of mass signals on materials surfaces.
