description Different types of carbon electrode materials for adsorptive stripping voltammetry are studied through the use of cyclic voltammetry. Capsaicin is utilised as a model compound for adsorptive stripping voltammetry using unmodified and modified basal plane pyrolytic graphite (BPPG) electrodes modified with multi-walled carbon nanotubes, carbon black or graphene nanoplatelets, screen printed carbon electrodes (SPE), carbon nanotube modified screen printed electrodes, and carbon paste electrodes. We compare the analytical performance of the different electrodes in terms of sensitivity and limit of detection, concluding that carbon electrodes modified with high surface area material exhibit an improvement of sensitivity. In terms of limit of detection, increasing the electrode surface area however does not improve the detection limit; the limit of detection is similar for all electrodes studied.
