Fourier Transform Infrared Spectrometer
model FT/IR-600 series

The new FT/IR-600 series is the top of the line in research grade FT/IR¡¯s. Designed to complement the recently released FT/IR-400 series the 600 series utilizes the same innovative Spectra Manager software running under Windows¢ç. The FT-IR-600 features a larger and more versatile optical bench to meet the resultion, sensitivity and wavenumber range requirements demanded in research grade FT/IRs.

Features

• Wide wavenumber range. One optical bench for Visible to far infrared.
• Very high sensitivity. Uses high aperture interferometer optics.
• Ample choice of beam splitters, light sources and detectors.
• Auto-alignment for fixed mirror. Allows easy beam splitter exchange by any operator.
• Affordable evacuable models eliminate N₂ purging and enhance sensitivity.
• Infield upgrade to FT/Raman, GC-FT/IR, TG- FT/IR, Micro FT/IR, etc.

Versatility
Three main FT/IR-600 models are available with either a purgeable or an evacuable interferometer

• Model FT/IR-610 with resolution down to 0.5cm^-1 for general research applications.
• Model FT/IR-615 with improved resolution to 0.25 cm^-1 for applications such as gas analysis
• Model FT/IR-620 featuring 0.25cm^-1 resolution, gold coated interferometer optics and fast scan capability. The logical starting point for expansion to FT/Raman.

Optical performance
Standard on all FT/IR-600 Spectrometers:

• Conventional Ge coated KBr beam splitter.
• Innovative, patented, high temperature ceramic source.
• High sensitivity, thermally insulated DLATGS detector.
• 28¡Æ incidence angle optics to reduce polarization effects with aperture system designed to achieve the highest optical resolution.

End purging while enhancing sensitivity
Unique for this range of instruments is the availability of three relatively inexpensive models with evacuable interferometers. Vacuum type FT/IRs (Models FT/IR-610V, 615V, and 620V) are usually considered the logical choice for far infrared applications: an expensive, by effective, alternative to conventional flushing with dry air and nitrogen. However, JASCO¡¯s three relatively inexpensive vacuum models are also well suited for mid infrared applications. Removing water and CO₂ absorption bands from the background allows higher sensitivity over the entire wavelength range.

Aluminum alloy casing enables vacuum operation
The aluminum alloy interferometer casing offers durability, stability and high sealing efficiency. Nitrogen purge capability is standard on all models of the 600 series while the 600V models can be efficiently evacuated by an inexpensive vacuum pump. The vacuum interferometer is more efficient at removing water vapor and CO₂ than the traditional purging by nitrogen or dry gas. The vacuum offers significant improvement not only in the far IR region but also in the mid IR where measurement is effected by absorption of water vapor. For the ultimate removal of vapor and CO₂ the All V models can be made fully evacuable including detector chamber and sample compartment. (Factory option)

Light sources, detectors, beam splitters
The FT/IR-600 Series can be equipped with a range of sources, beam splitters and detectors to expand the standard 7800 to 350 cm^-1 range to cover 15000 to 50 cm^-1. Three separate light sources can be incorporated in the unit including ceramic, Tungsten and high pressure Mercury. Up to four PC controlled detectors can be used, up to two within the main unit and two attached at the external port. Beam splitters can be exchanged by any operator and the auto-alignment feature adjusts for maximum throughput in about 15 minutes.

Rapid scanning
The rapid scan feature can acquire up to 20 scans per second allowing reaction profiles of rapidly changing compounds to be easily monitored. The kinetic change associated with an instantaneous adhesive. GC-FTIR also typically utilizes the rapid scan function to monitor GC separations. The rapid scan feature is standard on the FT/IR-620 and optional for the 610/615 models.

Vibration Isolation
All FT/IR-600 models feature a specially designed vibration insulator that completely separates the optical bench from both the upper and lower casing. This isolation provides extremely stable scanning allowing accurate measurement even during the highest sensitivity measurements.

FT/Raman Upgrade
The FT/IR-620 can be easily upgraded to measure FT/Raman by coupling the Model RFT-600 Raman attachment and a YAG laser (locally available). The Gold coated optics offer the highest throughput to provide the sensitivity demanded by Raman measurement. Both Micro and Macro FT/Raman can be measured and the sample stage allows both vertical and horizontal positioning.

Spectra Manager
The new Spectra Manager software allows control of a wide variety of instrumentation from the same common platform. Spectra Manager controls not only the FTIR series instruments but also V-series UV/VIS/NIR Spectrophotometers, J-Series CD/ORD Spectropolarimeters, and FP-750 Fluorescence Spectrofluorometer. The integrated package contains all the functions necessary to process all forms of spectroscopic data and frequently used functions can be conveniently accessed from user selectable tool bars. When measurement is completed, the analysis program is automatically started up, measurement data is transferred, and the spectrum is displayed in a view window.
