Interspec 200-X FTIR Spectrometer
Interspec 200-X FTIR Spectrometer
The Interspec 200-X FTIR spectrometer is a cost-effective Fourier transform infrared spectrometer and employs a number of unique features that ensure high performance from a compact instrument.
The Interspec 200-X measures just 59x39x19 cm and is regarded as one of the most compact and versatile infrared FTIR spectrophotometers.
The design of the 200-X is unique both in terms of optical design and the software and firmware, designed specifically to significantly reduce overall analytical times.
The interferometer geometry employs a new compact Michelson self compensating optical system that eliminates many of the optical alignment problems found in conventional type optical interferometers.
The Interspec 200-X 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.
The Interspec 200-X FTIR offers high S:N ratios and can provide SNR up to 15000:1. Resolution in the infrared is available 1 cm-1 and 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).
The Sample Compartment
The sample compartment is large 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 W20 X D26 X H16 cm. The optical axis is 74.5 mm above the base of the sample compartment and there is free space of 90 mm above the optical axis to the underside of the lid.
Sample Handling Accessories
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 Interspec 200-X series of instruments.
Extending Wavelength Ranges
To facilitate the use of more than one beam splitter or detector, the beam splitter and detector assemblies are interchanged allowing the Interspec 200-X to be used at any wavelength from 14000 to 400 cm-1.
|Beam Splitters||Range subject to coatings|
|KBr||7000 to 400 cm-1|
|ZnSe||5000 to 600 cm-1|
|Fused silica||14000 to 3000 cm-1|
The standard detector is a selected high sensitivity DLATGS pyroelectric design providing the highest possible signal to noise for all but the most demanding applications.
However there are many applications in infrared spectroscopy where high resolution analysis is required for materials with high absorption characteristics and for these applications cryogenically cooled MCT detector options are available each with a specific wavelength range.
In case of NIR spectral region two types of photodiodes are available: Si and InGaAs.

Air Cooled Infrared Source
The Infrared source is a long lifetime and trouble free operation device. The design achieves excellent wavelength emission characteristics and very high stability. The colour temperature of the source is ~ 11500C.
Desiccated and Sealed Interferometer
The Interspec 200-X employs a sealed and desiccated interferometer and detector compartment, ensuring high spectral integrity with low levels of water vapour within the interferometer.
