Scanning Electro-chemical Microscope

920D - CH Instruments, Inc. (CH)

The scanning electrochemical microscope (SECM) was introduced in 19891 as an instrument that could examine chemistry at high resolution near interfaces. By detecting reactions that occur at a small electrode (the tip) as it is scanned in close proximity to a surface, the SECM can be employed to obtain chemical reactivity images of surfaces and quantitative measurements of reaction rates.
