The history of the JASCO instruments measuring in the infrared range began in the mid-50s with the creation of the dispersive spectrometer named DS-101. Since then the experiences gathered for more than half a century have been applied to design the FT/IR-4000 and 6000 spectrometer series. The FT/IR 4000 series have been primarily developed for routine measurements, while the 6000 series serve the research applications and both have a large number of sample holders and accessories: from the simple film holders to the multi-channel microscopes with fast surface mapping.
The control of the instruments is provided by the Spectra Manager II software package, which controls all the JASCO spectroscopic instruments. The Know-it-All program package with a spectrum library of 10 000 spectra belongs to each standard FT/IR instrument. The software is able to read the most important spectrum formats and it has different spectrum search and management features. User-built spectral libraries can be prepared with it and it is capable for analysis of functional groups and chemical structures and preparing reports, as well.
FT/IR – 4600 and 4700
These instruments are primarily recommended for routine and 
educational purposes which cover the 7800-350 cm-1 infrared range in their standard configuration. However, this range can be extended to 15,000-2,200 cm-1 or to 5000-220 cm-1. The standard setup of each instrument includes automatic beam-splitter alignment, variable aperture, the total inert purging option and the possibility of automatic validation. Due to the optional MCT detectors, they can be converted into “rapid scan” instruments of even 10 scan/sec.
FT/IR – 6600, 6700 and 6800
The FT/IR-6000 instruments designed for research and development with their extension options are able to extend the standard 7800-350 cm-1 measuring range to the far and near infra-red range. In the maximum configuration the covered wavelength range can be even between 25,000-10 cm-1. The standard setup of each instrument includes automatic beam-splitter alignment, variable aperture and total inert purging option. The measurements in the far-infrared range are facilitated by the full-vacuum option. Using the automatic beam splitter changer unit capable of taking in 4 beam splitters and the automatic interferometer window changer unit together the measurements will be possible in wide wavenumber range without the user’s manual intervention. The 20 scan/sec “rapid scan” measurement method is part of the standard configuration of the 6800 instrument which has gold coated optics, while with the 6600 and 6700 instruments it can be found among optional expandability possibilities.
Spectra Manager II for FT/IR instruments
The control of the instruments and data processing is provided by the Windows-based Spectra Manager II multifunctional software. The operational functions cover the settings of the measurement parameters and their storage, real-time spectrum display, scale change, zoom functions, smoothing, baseline correction, CO2 and water vapor compensation, ATR correction, peak search, peak height and peak area calculation, arithmetic operations, derivatives, %T/Abs conversion, KM and KK conversion, automated spectral subtractions, JCAMP and ASCII conversion, printing template editing etc. The 21 CFR Part 11 compliance support version can be ordered optionally, as well as the PCR, PLS, PCA, CLS multicomponent analysis software packages.
A wide range of sample holders is available for carrying out the FT/IR measurements. With the selection of the appropriate sample holder and measuring method, the spectral properties – in the infrared range – of materials with the most disparate physical state, temperature and optical properties can be defined. For the JASCO FT/IR JASCO instruments we offer a wide range of JASCO, Pike and Specac sample holders and accessories as well, from presses used for the preparation of KBr pellets, through gas cells and ATR accessories to FT/IR microscopes.
