<p>A scanning probe microscope (100) includes an electrochemical liquid cell (106). Three supporting mounts (92) extend downwardly from a frame (102) and include magnetic balls (154) to which a sample platform (90) is attached. Two pegs (94) extend downwards from the frame (102) and engage at apertures (132) thereghrough. A bore (194) in the frame (102) is provided through which a scanner (104) is inserted to engage a sample (116) on the platform (90). A hermetically sealed chamber (112) is formed around the sample (116) by a seal between the scanner (104) and the frame (102) at an O-ring seal (160). The fluid cell (106) is attacted to the sample platform (90). Electrochemical control of the potential of the sample (116) and a probe (260) is used to control interactions between the probe (260) and a surface of the sample (116). Contamination of the surface of the sample (116) is controlled by placing the probe (260) and the sample (116) under a protective fluid.</p> |
