8.4.3.1 Linear sweep voltammetry
As noted above, quantification of the analyte in ASV comes from
the stripping step. Different methods of quantification are available,
based on different ways of scanning the potential. The simplest
method is linear sweep voltammetry (LSV), in which the potential
waveform is a linear increase as illustrated in Fig. 8.6a. For an MFE,
