Nicolet Series II Magna-IR System 750 FTIR


FTIR spectroscopy is used for structural characterization of organic and inorganic molecules in solids, liquids, gases, and on surfaces.  Qualitative and quantitative information about the molecule may be obtained.


  • Nicolet Series II Magna-IR System 750 FTIR
  • Microscope offers 15 µm lateral spatial resolution
  • Spectral range coverage from 9600-350 cm-1
  • Spectral resolution to 0.125 cm-1
  • Windows-based OMNIC® software for data collection and analysis

Equipment and applications:

  • Thermo Scientific Nicolet iS50 FT-IR spectrometer with a built-in diamond attenuated total reflection (ATR). The detectors on the main bench are MCT-A (11,700 - 600 cm-1) and DLaTGS (12,500 - 350 cm-1). The detector on the ATR is DLaTGS.
    • On the main bench, transmission, specular reflection, diffuse reflection and multi-bounce ATR measurements are conducted.
    • The built-in diamond ATR is for single-spot ATR measurements.
  • Thermo Scientific Continuum IR microscope with transmission, reflection and attenuated total reflection (ATR) objectives. The detector is MCT-A.
    • IR microscopy is used to analyze micrometer-sized spots and generate a chemical map by scanning an area of a sample. The aperture size can be varied from ca. 20 to 150 micrometers. The motorized x-y sample stage's travel limits are 12 cm x 6 cm.
  • Smart ARK 12 bounce HATR module with a 45 degree ZnSe flat crystal and a 45 degree Ge flat crystal.
    • Multi-bounce ATR is typically used to analyze thin films. Comparing to single bounce ATR, the IR signals in multi-bounce ATR are stronger due to multiple-time interactions of the IR beam with the samples.
  • Diffuse and specular reflection accessories for reflection measurements.
