I'm currently researching the topic and seeking clarity on the process. Specifically, I'd like to understand how it differs from traditional analytical calibration curves and whether the resulting curve must show linearity. Could you also please provide guidance on conducting a calibration curve using square wave voltammetry?
Here are the key steps to perform a calibration curve using square wave voltammetry:
The key difference from a traditional calibration curve is that the analytical signal is peak current rather than UV absorbance or other measurement. Linearity is still ideal, but the relationship does not always need to be perfectly linear depending on your analyte and concentrations. You can employ data transformations or non-linear curve fitting if needed.
