General

The Interspec 308 series of FTIR portable spectrometers represent a cost effective Fourier transform infrared portable spectrometers and employ a number of unique features that ensure high performance from a compact instrument.

The Interspec 308 measures just 49 X 39 X 20 cm and is regarded as one of compact and versatile infrared FTIR spectrophotometers. The design of the 308 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 pendulum type roof mirrors optical system that eliminates many of the optical alignment problems found in conventional type optical interferometers.

The Interspec 308 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 Sample Compartment

There is no sample compartment in classical sense. Sample compartment is integrated inside the instrument allowing to carry out one or three bounce ATR , transmission or reflection measurements.

Interferometer Performance

The Interspec 308 series of instruments employ a sealed and desiccated pendulum type roof mirror interferometer, ensuring high spectral integrity with low levels of water vapour within the interferometer.

We also offer a version (308Z) that employs a ZnSe non-hygroscopic optics (beamsplitter and compensator) to be impervious to humidity. Resolution in the infrared is available up to 2 cm-1. The overall wavelength range is 7000 to 400cm-1 (KBr) or 5000 to 600 cm-1 (ZnSe).

Sofware

Interspec for Windows is supplied on CD 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 modelling 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 import and export is possible in ASCII, Excel, SPC or JCAMP formats. Other FTIR spectroscopic softwares like Essential FTIR or Panorama for running the spectrometer and for complete handling of measured infrared data are available as an option.
