Fast Cyclic Voltammetry (FCV)

Fast Cyclic Voltammetry (FCV) of Fast-scan cyclic voltammetry (FSCV) is cyclic voltammetry with a very high scan rate (up to 1×106 V·s−1). 

Application of high scan rate allows rapid acquisition of a voltammogram within several milliseconds and ensures high temporal resolution of this electroanalytical technique. An acquisition rate of 10 Hz is routinely employed.

In our instruments, additional options for Fast CV compared to a normal CV include averaging multiple scans and using equilibration scans. This technique can be particularly useful for very noisy measurements. Of course, it would be preferable to eliminate noise at the source first.

Auto-ranging cannot be used at these high speeds, so only one current range should be selected.
