FTIR Spectroscopy

FTIR SpectrometerThe Thermo Scientific Nicolet 8700 FTIR Spectrometer with Continuµm Imaging System is a research-quality tool providing superior performance and advanced scanning capabilities over other FTIR instruments. Our system is equipped with some additional accessories, including the Smart iTR module, an ultra-high-performance, versatile Attenuated Total Reflectance (ATR) sampling accessory.

FTIR is the standard for chemical identification work in academic, analytical, QC/QA, and forensics laboratories.  FTIR can determine the various organic and inorganic compounds within a sample (food, soil, metals and their alloys, polymers, etc.) based on their unique IR absorbance spectra.

Benefits of FTIR:

  1. Rapid and non-destructive
  2. Little sample preparation
  3. Complementary to Raman
  4. Easy access to low vibrational frequencies, making it easy to analyze inorganic molecules
