Key Difference: Pulse Voltammetry vs. Differential Pulse Voltammetry
Pulse voltammetry and differential pulse voltammetry are both electrochemical techniques used for analyzing redox reactions. Here is the main difference between the two:
Pulse Voltammetry:
- In pulse voltammetry, a periodic potential pulse is applied to the working electrode.
- The current is measured at the beginning of each pulse, providing information about the redox reactions happening at that moment.
- This technique is useful for studying fast reactions and can provide information about the kinetics of the redox reaction.
- Pulse voltammetry is often used for qualitative analysis, as it can give insights into the nature of the redox species present in the sample.
Differential Pulse Voltammetry:
- In differential pulse voltammetry, a constant potential is maintained at the working electrode, and short potential pulses are applied periodically.
- The current is measured at the end of each pulse, allowing for the detection of small changes in current that can be attributed to the presence of specific redox species.
- This technique is particularly useful for quantitative analysis, as the differential current peaks can be correlated with the concentration of the redox species in the sample.
- Differential pulse voltammetry is often used in analytical chemistry for the determination of trace amounts of analytes in solution.
In summary, while pulse voltammetry focuses on measuring current at the beginning of potential pulses for qualitative analysis, differential pulse voltammetry measures current at the end of pulses for quantitative analysis.

The main difference is that in pulse voltammetry, current is measured only at the beginning of the pulse, whereas in differential pulse voltammetry, it is measured at the end of the pulse. This difference allows for improved sensitivity in differential pulse voltammetry.
