IR Studies of Oxide Surfaces Using DRIFT
Fourier Transform-Infrared Spectrometer (FT-IR)
Nicolet Nexus 670
FT-IR spectroscopy is used for molecular characterization of solids, liquids, gases, and on surfaces. The diversity of materials that the FT-IR can examine and the ease of sample preparation are what makes it so appealing.
Features:
- 11,000 - 375 cm-1 Range
- 0.125 cm-1 Resolution
- Transmission, ATR and DRIFT operation available
- DTGS detector
FT-IR is currently optimized for mid-IR spectroscopy.
Time needed to collect data under best resolution is 8 minutes.
ATR accommodates flat samples such as polymer films and requires little sample preparation.
DRIFT provides surface analysis of powders and particles. Sample concentrations can range from parts per thousand to neat.
