Amplitude modulated flow analysis for speciation—Proof of concept by quantification of Fe2+ and Fe3+ ions
We propose a novel concept of flow-based analysis for spectrophotometric speciation based on flow rate modulation and fast Fourier transform (FFT). A redox reagent solution's and a sample solution's flow rates are varied by sinusoidal control signals with periods of T and 0.5T, respectivel...
