Electrochemistry of the synthetic tryptamine 5-MeO-MiPT at glassy carbon and screen-printed electrodes: A rapid and simple screening method for application in forensic analysis

First report on the electrooxidation of vinpocetine using a modification free sensing platform: application to pharmaceutical formulations

“…The square wave voltammetry (SWV) experiment was conducted to obtain the W 1/2 (0.113 V) of VIN on GCE (Fig. S3C†), 49 thus allowing the calculation of α to be 0.388, as per the following equation:where ( n ) is the number of transferred electrons, ( R ) is the ideal gas constant (8.314 J mol −1 K −1 ), ( T ) is the temperature (298.15 K), ( F ) is Faraday's constant (96 485.33 C mol −1 ), ( α ) is the electron transfer coefficient, and ( θ ) is the angular coefficient found for the linear regression ( θ = 16.096). The number of electrons ( n ) was calculated according to the following equation:corresponding to ca.…”
