FTIR Analysis in OriginPro | Baseline Correction, Smoothing, Peak Labeling | Graphene Oxide Tutorial

In this detailed FTIR tutorial, expert researcher Dr. Ranjana Verma walks you through a complete FTIR analysis workflow in OriginPro — from raw data to publication-ready plots. This video is part of InSciLabTech’s new initiative “For Researchers by Researchers”, where real scientists share the exact methods they use in their own research work. 🔬 You Will Learn 1. Importing FTIR raw data into OriginPro 2. Correctly converting % Transmission → Absorbance for baseline correction 3. Applying a realistic, user-defined baseline 4. Fixing negative absorbance values (two scientific methods explained) 5. Smoothing spectra using the Savitzky–Golay method 6. Converting processed data back to % Transmission 7. Professional plot formatting and axis labeling 8. Peak identification and labeling for Graphene Oxide 9. Exporting high-resolution (300 DPI) images for research papers & theses ⏱️ Chapters 00:00 Initiative Introduction & Content 00:40 Importing FTIR Data 01:12 Why & How to Convert %T to Absorbance 02:35 User-Defined Baseline Correction 04:08 Fixing Negative Absorbance 05:49 Converting Back to %T 06:34 Smoothing (Savitzky–Golay) 07:40 Formatting the Graph 09:25 Labeling FTIR Peaks 10:20 Exporting the Final Plot 🛠️ Software OriginPro 2024 (Steps apply to most older OriginPro versions as well) 🧪 Sample Used Graphene Oxide (FTIR Spectrum) 📂 Practice Data Please ask in the comments or visit our community hub to request the data.
