If your sample is dissolved in a solvent, or if you need to look at a contaminant on a substrate, you can subtract the pure reference spectrum from your sample spectrum.
Automatically labels the exact wavenumbers of your highest intensity peaks based on a threshold you define.
Set the number of co-added scans. For routine screening, 16 to 32 scans balance speed and quality. For high-signal-to-noise research, use 64 to 128 scans. Resolution: Select the spectral resolution. is standard for solids and liquids. Use | Version | Release Date | Key Features
Wait for the scans to complete. The system will store this in its temporary memory. Step 3: Collect the Sample Spectrum
To determine the concentration of a specific component within a mixture:
Ensure your sample compartment or accessory (such as an Attenuated Total Reflection, or ATR, crystal) is completely clean. Residual chemicals from previous tests will contaminate your data. Clean the surface with an appropriate solvent (e.g., Isopropanol or Acetone) and let it dry completely. Step 2: Collecting the Background standard data processing steps
Place your sample onto the accessory. If using an ATR, apply the appropriate pressure using the slip-clutch tower. Click . Enter a unique title for your sample when prompted.

Minimizes residual sharp peaks caused by ambient H₂O vapor and CO₂ variations in the room.
OMNIC 9 is a versatile platform that balances ease of use for routine operators with deep configuration options for advanced spectroscopists. By mastering proper experiment setup, standard data processing steps, and structured library searches, you can extract reliable, high-quality analytical insights from your FTIR system. Regular system calibration and accurate baseline management remain the best approaches to generating reproducible, publication-ready spectral data.
