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

Usage Guidelines

FTIR Analysis

1. Sample Preparation

   • Use ATR for nanoparticles
   • Ensure good contact for ATR
   • Consider KBr pellet for transmission

2. Spectrum Analysis

   • Identify characteristic bands
   • Compare to reference spectra
   • Quantify using Beer-Lambert

3. Surface Chemistry

   • Monitor ligand exchange
   • Verify functionalization
   • Detect degradation products

Process Integration

• Multi-Modal Nanomaterial Characterization Pipeline
• Nanomaterial Surface Functionalization Pipeline
