🔬 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!
