The TEO-200 series of FTIR spectrometers represent a low cost Fourier transform infrared spectrometers and employ a number of unique features that ensure high performance from a compact instrument. The TEO 200 measures just 590 X 390 X 190 mm and is regarded as one of compact and versatile infrared FTIR spectrophotometers. The design of the 200 is unique both in terms of optical design and the software and firmware designed specifically to significantly reduce overall analytical times. The interferometer geometry is employing a new compact Michelson self compensating optical system that eliminates many of the optical alignment problems found in conventional type optical interferometers.
The TEO-200 design avoids the use of conventional corner cube optics and dynamic alignment. In practice this means that the instrument can be used in the research laboratory, in any university or college environment and if required, can also be used outside laboratory or in remote locations.
All TEO FTIR instruments offer high S:N ratios and can provide SNR up to 15000:1. Resolution in the infrared is available 1 cm -1 programmable up to 32 cm -1 (option 0.5 cm -1). The overall wavelength range is 7000 to 400cm -1 (IR) or 14000 to 3000 cm -1 (NIR).
As you will see the sample compartment is large indeed and can accommodate all of the normal sample handling requirements relating to FTIR spectroscopy. This unique compartment will also accommodate the wide range of accessories supplied by specialist accessory manufacturers. Overall dimensions are W200 X D224 X H154 mm. The optical axis is 74.5 mm above the base of the sample compartment and there is free space of 95 mm above the optical axis to the underside of the lid.
In order to facilitate the use of more than one beam splitter or detector, provision has been made to interchange the beam splitter and detector assemblies allowing the TEO-200 to be used at any wavelength from 14000 to 400 cm-1.

The software is supplied and provided with each system shipped. The software includes features for all standard analytical requirements including manipulation of spectral data, instrument control, plot with preview on the screen plus many others. Also included are several facilities for analytical modeling of interferogrammes or spectra, with smoothing, and baseline correction, interactive editing and data manipulation . Also spectral subtraction, mixture subtraction, smoothing derivatives, plot with preview etc. Data input and output is possible in ASCII or JCAMP. Other commercial programmers can be used like Essential FTIR or Panorama for features such as Library Search.
Our unique software has been designed specifically for multi function applications, it is easy to use and it is provided free of charge. The utility of the software programme can be extended by adding other commercial programmes such as search, component identification, Kramers Kronig Transform, Chemometrics, etc. to suit individual requirements.
The applications for FTIR are extensive and more use is being made of these techniques now than at any other time.
Many of these new applications can be attributed to the development of a very large and comprehensive range of sample handling accessories made available from many accessory companies. All such accessories can be used in the TEO 200 series of instruments.
So no matter what your sample is, we are able to offer just the right sample mount including accessories for ATR accessories, specular reflection, diffuse reflectance, DRIFT, photo acoustic, liquid sampling, gas cells, gas purge systems, hydraulic or hand help sample presses, film making kits, sample grinders, micro sampling, disposable cells, polishing kits, polarizers, plus a lot more.
