A Comprehensive Examination of Voltammetric Parameters in Fourier Transform Sine‐wave Voltammetry (FT‐SWV) Leading to Concentration Linearity and High Signal‐to‐background Ratio

Abstract

There has not been a comprehensive investigation of the effect of voltammetric parameters: amplitude, dc bias potential, and excitation frequency of the sine waveform in Fourier Transform Sine-Wave Voltammtery (FT-SWV) on background, signal, and signal-to-background ratio as well as linearity with respect to the concentration of an analyte. FT-SWV of ruthenium hexamine (III) chloride (RuHex) demonstrates that the dc bias potential can be used to adjust the phase angle difference between the signal and background to obtain out-of-phase background. Several conditions show a high signal-to-noise ratio and good concentration linearity. The lessons from RuHex guided us to conditions for good signal-to-background ratio and concentration linearity for dopamine (DA). Keywords: sine-wave voltammetry • FT-SWV • signal-to-background ratio • phase-sensitive detection • out-of-phase background [a] Y.

“…Then, the established one-dimensional unsteady heat conduction model is solved by combining the bounded difference to obtain an approximate numerical solution and then dropping the substitution again. We put the initial conditions of formula ( 6 ) to take the Fourier sinusoidal transformation to translate the initial value problem of the normalized equation containing the parameter [ 28 , 29 ].…”
