• The FT-IR 850 Bench is equipped with specific sets of beamsplitter/detectors:
  • ability to work in the
    • Mid-IR (400 - 4,000 cm-1) --- framework basicity
    • Near-IR (4,000 - 12,500 cm-1) --- defect SiOH
    • Far-IR (10 - 400 cm-1) --- cations translations
  • cells allowing in-situ measurements both in transmission and in reflection
  • Diffuse Reflectance (DRIFTS) --- highly opaque or weakly absorbing samples
  • Photoacoustic (PAS) --- opaque samples
  • Attenuated Total Reflectance (ATR) --- optically dense materials
  • Wire Grid Polarizer available for ATR
  • Hydraulic Pellet Press. 13mm pellet die/maker available upon request
• FT-Raman Module:
  • Organic/Inorganic interactions in hybrid materials
  • Organics trapped in layered and porous framework
  • Experiments to check the validity of simulated results (Force Field, etc.)
  • Works with powder, and liquid samples. Not capable of thin film measurements.
  • Sample Tubes: 5mm O.D. NMR tubes are the easiest to use. The dimensions should be as follows:
    • Max Tube Height = ~45 mm
    • Minimum Sample Height = ~13 mm
      However, if limited sample is available, then a ~6 mm spacer can be used and only ~4mm of sample is required
  • HeNe Laser Wavelength = 1064 nm.
• Regulations and Procedures for Using IR or Raman.

The IR/Raman laboratory is equipped with a vacuum line and other gas lines (He, N2, O2, Air, etc.) which allows simple sample preparation and the ability to perform in-situ studies on the IR/Raman spectrometer.

Training

Everyone must first be trained on the instrument before using it. Please fill out the Training Request Form and indicate which instrument(s) you would like to do; please check all that apply.
