SPM-8100FM

The new HR-SPM scanning probe microscope uses frequency detection.
This instrument is not only capable of ultra-high resolution observations in air or liquids, but for the first time enables observations of hydration/solvation layers at solid-liquid interfaces.

HR-SPM: High Resolution Scanning Probe Microscope

Observations were made of the arrangement of atoms on a NaCl surface in a saturated aqueous solution. Atoms hidden by noise in existing AFM observations (AM method, left) are clearly visible when the FM method (right) is used. The FM method provides true atomic resolution.

KPFM: Keivin Probe Force Microscope

Pt catalyst particles in a TiO₂ substrate were identified, and the surface potential was measured using a KPFM. Pt particles several nm in size were observed in the exchange of charges with the substrate. In the figure on the right, the red circles indicate positive potential, and the blue circles indicate negative potential. It is evident that the resolution has been dramatically improved, even for a KPFM.
 

Note: KPFM functionality is available on a special order basis.
