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
