Description
separation = anodicPeak-cathodicPeak; midpoint is their arithmetic mean; referenceGap = separation-referenceSeparation.
Electrochemical potentials require a common reference electrode, unit and sign convention. Endpoint differences and scan partitions are record operations; changing the reference scale or correcting drift needs explicit supplied offsets.
separation = anodicPeak-cathodicPeak; midpoint is their arithmetic mean; referenceGap = separation-referenceSeparation.
When to use this tool
Use Cyclic Voltammetry Peak Separation Gap when checking a supplied potential reference or scan-boundary convention.
How to use the tool and how it works
- Enter anodicPeak, cathodicPeak, referenceSeparation. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read separation, midpoint, referenceGap. Use the output convention below.
Require anodicPeak >= cathodicPeak and nonnegative referenceSeparation. separation = anodicPeak-cathodicPeak; midpoint is their arithmetic mean; referenceGap = separation-referenceSeparation.1

}Limitations and assumptions
- Peaks share a potential unit and reference. This arithmetic does not detect peaks, correct resistance or establish reversibility from the gap alone.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use calibrated references and full recorded waveforms when drift, reversal detection, peak fitting or experimental interpretation matters.
