A Bruker Vertex 70v FT-IR spectrometer attached to a Bruker HYPERION 2000 FT-IR microscope allows us to perform Transmission/Reflection/Absorption measurements in a spectral range of 24000 - 10cm-1 (0.3-720THz), covering a wide frequency range from far IR to visible regime.

• Using the above FT-IR spectrometer, we can characterize thin films, powders or liquids, either under vacuum, or in ambient air.
• Transmission measurements can be performed at several angles of incidence, varying from 0˚ to 90˚.
• Reflection measurements can be done using the A 513/Q specular reflection setup at several angles of incidence, varying from 13˚ to 83˚.
• The Vertex 70v FT-IR spectrometer is equipped with a A225/Q Platinum ATR unit with single reflection diamond crystal which allows the infrared analysis of unevenly shaped solid samples and liquids through total reflection measurements, in a spectral range of 5500 - 10cm-1 (0.3-165THz), at temperatures up to 350°C.
• A Linkam FT-IR 600 heating and freezing stage with a temperature range of -196°C to 600°C and heating rates up to 150°C/min can be coupled to our Vertex 70v FT-IR spectrometer, or the HYPERION 2000 FT-IR microscope.
• Using both the spectrometer mentioned above, linearly (and circularly) polarized transmission (and reflection measurements) can be performed, from far IR to visible regime, using several sets of linear grid polarizers, or circular polarizers using super-achromatic quarter-wave plates with an accuracy of λ/4±14%.
• A Thermo Spectra-Tech High Pressure Vacuum chamber allows the exposure of the samples to extreme reaction conditions, at temperatures up to 900°C at ambient pressure, or at lower temperatures up to 400°C at up to 1500 psi, providing a stability of ± 1°C.

This way samples can be tested for various applications, such as:

• Control of sampling environment of solid samples
• In-situ measurements
• Adsorbate characterization
• Catalysis studies
• Dehydration kinetics
• Solid-solid phase transitions
