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

Описание: 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
