Optimizing Amplitude in Square Wave Voltammetry
In this video, the focus is on optimizing amplitude for square wave voltammetry experiments, using ferrocyanide as the model system. The presenter demonstrates the process, highlighting key parameters such as the start voltage (-200 mV), stop voltage (600 mV), potential step (5 mV), current range, and frequency (fixed at 25 Hz).
After setting up the experiment, the data is collected using the SenseIt potentiostat and analyzed on the Julie platform. Steps involved include:
- Baseline Subtraction: Normalizing raw data to address baseline offsets.
- Peak Height Analysis: Extracting values for different amplitudes (5 mV to 200 mV) to observe how amplitude impacts peak height.
The results show that while higher amplitudes increase peak height, the changes are not drastic. The video emphasizes the importance of quick assays for real-world applications, with a focus on efficient data collection and analysis using connected software tools.
