🔬 Video Title: Cyclic Voltammetry Demo with SenseItAll (SIA) Potentiostat
Welcome to this quick demonstration! In this video, I’ll be performing cyclic voltammetry (CV) using a 5 mM potassium ferricyanide solution on a screen-printed carbon electrode (501 model). I’ll run the experiment first, then break down the process and analysis step-by-step.
📌 Key Sections:
✅ Live Experiment: Recording three CV cycles at 100 mV/s scan rate
✅ Cloud Data Upload: Real-time results sent to Djuli database via the SenseItAll (SIA) app
✅ Advanced Processing: From raw data to concentration values
✅ Full Walkthrough: Understanding how to analyze electrochemical data
⚙️ Experimental Parameters:
-
Potential Range: +600 mV to -200 mV
-
Scan Rate: 100 mV/s
-
Cycles: 3
-
Current Range: 100 µA
📊 Data Analysis Steps:
1️⃣ Crop to relevant potential window
2️⃣ Baseline correction (iterative polynomial)
3️⃣ Peak detection (~10 mV oxidation peak)
4️⃣ Concentration conversion using calibration
🌍 Why This Matters:
The SenseItAll (SIA) system transforms electrochemical signals into actionable data – not just graphs, but actual concentration measurements. This is the future of accessible electrochemistry!
