Micro electrodes

Micro Pt electrode 10Ám

Advantages of using Microelectrodes for CV measurement

1. Little distortion from dissipation in potential or electrification flow
2. Combination of PC enables to process at high sweep rate
3. Analyzable short-lived intermediate in electrode reaction
4. Mearsurable without support electrolyte
5. Excellent measuring accuracy because of little influence of noise arise from electrification flow
6. Diffusion is smooth enough to obtain stationary state


 

Figure in right : the result of
detection of a chemical product
in subsequent reaction. By the
fast sweep at 104V/S, the peak
(which is shown when the
short-lived intermediate is
reduced into the former
substance) can be observed
before the intermediate
vanishes.
