Model: Shimadzu FTIR 8400S

FTIR spectrometer used to study the fluctuation in the molecular structures, to determine the purity of nature, to speculate about the the symmetry of the molecule or to do quantitative analysis.

  • The advantages of using infrared measuring method compared with other structural analyzing methods (X-ray diffraction, electron magnetic resonance ...) are to provide information about the molecular structure quickly, does not require complex calculation.
  • FTIR contains Michelson interferometer, the light source is Nerst lights / global lamps continuously emitting infrared radiation.
  • Identify and quantify materials: organic compounds, structures, defining homogeneous materials
  • Ability to analyze: adhesive performance, dosing small cast device, layered materials, chemical corrosion.
  • Quality Control Display: Comparison of sample, quantitative way, comparing material from many different samples.
