Bruker Invenio-S FTIR Spectrometer

Fourier-transform infrared spectroscopy for chemical analysis


Location: Jesser Hall 162

Bruker Invenio-S FTIR spectrometer for compound identification and the determination of sample chemistry/molecular bonding for solids, films, powders, liquids, and suspensions.


Bruker FTIR Technique Summary:

  • Nondestructive interferometric compositional measurement of molecular vibrational modes
  • Minimal or no sample preparation required
  • Single-reflection attenuated total reflectance (ATR) for measurement of surface properties of solids, thin film samples (approx. 0.5-2 microns), and liquids
  • Transmission spectroscopy for characterization of IR-transparent films
  • Diffuse reflectance spectroscopy with Pike Technologies EasyDiff accessory for compositional analysis of powders and rough surfaces
  • OPUS 8.0 integrated evaluation, data processing (identification and quantification) and report generation software with spectral library
  • Variable spot size: 0.25 - 8 mm diameter
