reduction. At potentials well positive of the redox potential, there is no faradaic
reaction is response to the pulse, so the differential current is zero. At potentials
around the redox potential, the differential current reaches a maximum and decreases
to zero as the current becomes diffusion-controlled. The current response is therefore
a symmetric peak (Figure 10-15).
Figure 10-15. Typical current response for DPV/P.
The sensitivity of DPV/P is intermediate between NPV/P and SCP (20 µA/mM), but
the detection limit of DPV/P is significantly lower (10
discrimination against the charging current.

General Parameters
Initial E (mV) = 0
Final E (mV) = 0
Sensitivity = 1µA/V
Specific Parameters
Scan Rate (mV/s) = 4
Sample Width (msec) = 17
Drop Time (msec) = 1000
Quiet Time (sec) = 2
Comments
a) Increasing the Sample Width can reduce noise.
b) The step height (or sampling interval) is the product of the Scan Rate and the
Dropping Time (e.g. the default values is 4 mV).
