Principle of FTIR 6x, 8x

The FT/lR-6X and FT/lR-8X spectrometers offer a highly configurable optical system applicable to virtually any FTIR application, from simple Mid IR measurement to more complex analysis in the farthest reaches of the electromagnetic spectrum.
Research-based measurements are easily performed on the FT/lR-6X or FT/lR-8X spectrometers with options such as full-vacuum, gold-coated optics, rapid & step scan and FT-Raman for more advanced experiments.
Exchangeable elements combined with full automation can be used for spectral measurement from 25,000 cm-1 to less than 20 cm-1 without touching the system.
The FT/lR-6X and FT/lR-8X spectrometers are compatible with a range of vacuum
and configurable emission ports to perform experiments outside the sample
compartment, and are also compatible with our comprehensive range of IR
microscopes.
Vacuum option
When measuring in the IR range, eliminating the effects of water vapor in the instrument is extremely important for obtaining highprecision data.
Although purging with dry air or nitrogen gas is the conventional solution to this problem, the FT/IR-6X and FT/IR-8X have options for a full or partially evacuable optical system.
This system can be used for performing low ppb-level water vapor monitoring, thin-film measurement and dilute solution measurement.
Where measurement across wide spectral regions is required, automatic window and/or beam-splitter exchange can be included for uninterrupted spectral acquisition.

Rapid scan and step scan options
For time-resolved
measurements, Rapid scan option is available for FT/lR-6X and FT/lR-8X. Rapid
scan provides measurement up to a maximum of 40 Hz.
Step scan measurement options are also available for FT/lR-8X. Step scan offers microsecond and/or nanosecond measurement options.
Step scan measurements require an infinitely repeatable and reproducible experiment. Some key application examples include:
-
Depth profiling with PAS
-
Thin film measurements with PM-IRRAS
-
Chemical transitions in the electric field orientation of liquid crystals
-
Materials rheology with polymer stretching
-
Protein folding
Wavelength range
The FT/lR-6X and FT/lR-8X spectrometers can be configured for any spectral region within the measurement range 25,000 cm-1 to less than 20 cm-1.
Automatic beam
splitter and window exchange allow uninterrupted measurement across the entire
spectral range.
