Flow Profile in Flow-Injection Analysis
When we first inject a sample into an FIA’s carrier stream it has the rectangular flow profile of width w as shown below in (a). As the sample moves through the mixing zone and reaction zone, the width of its … Continue reading
Origin of Faradaic Current in Voltammetry
Let’s assume we have a solution that is 1.0 mM in Fe(CN)63– is 1.0 mM. The standard state potential for the reduction of Fe(CN)63– to Fe(CN)64– is +0.356 V. If we apply a potential of +0.550 V the concentration of Fe(CN)63– at the electrode’s surface … Continue reading
