All Thermo Scientific FTIR spectrometers are now cloud-enabled, so you can view and share data anytime, anywhere.

Use Fourier transform infrared (FTIR) spectroscopy to

  • Identify unknown materials (e.g., Forensics, Art restoration, Counterfeit testing) 
  • Conduct contaminant analysis (e.g., Analytical Services, Gemology) 
  • Reverse engineer new products (e.g., Materials Science research) 
  • Verify chemical structure and mixture compositions (e.g., Quality Assurance)
