FTIR Analyzer
Purpose
The FTIR Analyzer skill provides molecular characterization of nanomaterials through infrared spectroscopy, enabling identification of functional groups, surface modifications, and chemical bonding.
Capabilities
- ATR-FTIR for nanoparticle surfaces
- Functional group identification
- Surface modification verification
- Gas-phase FTIR for reactions
- Diffuse reflectance (DRIFTS)
- Spectral library searching
