FTIR Spectrometer



Keit IRmadillo FTIR Spectrometer

Fourier Transform Infrared (FTIR) spectroscopy enables material identification by measuring the amount of light in the mid-infrared region absorbed at the molecular level. Specific molecular bonds absorb light at specific frequencies. Different compounds have different absorption fingerprints, which arise due to the unique combination and relative strengths of each compounds’ absorption frequencies.

FTIR spectrometers pass light through the sample of interest, splits it into two beams and introduces a path length difference before re-combining the beams to generate an interference pattern. A Fourier transformation of the pattern yields the constituent wavelengths of the original input beam – and thus the chemical fingerprint is identified.

Orange-Tri Product Information

Keit has developed the IRmadillo ™ as a rugged FTIR spectrometer based on a novel optical design. The spectrometer’s structural simplicity results in a uniquely compact and robust device for operating in tough manufacturing environments. Vibration tolerant, the Keit FTIR was originally developed to be fitted to a satellite.  The resulting qualities have made the IRmadillo™ FTIR spectrometer an ideal analytical instrument for process monitoring and control for industrial applications.


SKU# IRmadillo

Solid-State Spectrometer
The IRmadillo™ FTIR spectrometer is a solid-state instrument certified for use in hazardous and explosive environments. Mounted directly on, or in-line with, manufacturing vessels, the instrument excels at continuous monitoring of industrial liquids and slurries.

Faster Results as They Happen

No need to wait for your results. With an in situ sensor to monitor your reactions live, the Keit IRmadillo™ tells you what your reactions are doing as they happen rather than after they happen — and where ever they happen!  No more need to wait for your analysis results to return from remote sampling techniques such as with HPLC or GC.

Innovation in Process Monitoring & Control

Standard FTIR analytical instruments are highly sensitive to vibration and ambient temperature— making them a challenge to use outside or on the manufacturing floor.  Keit offers an innovative solution for continuous monitoring of your processes in real-time over a variety of industrial applications – from detecting the quantity of water in glycol at a petro-chemical plant to measuring sugars and alcohol in a fermentation vat.
