Include many features found in the research grade FT/IR-6000 Series

FT/IR-4000 Series of FTIR Spectrometers

FT/IR 4000 SeriesThe FT/IR-4600 is a powerful Mid-IR FTIR spectrometer (wavenumber range 7800 to 350 cm-1), with many features that you find in a research grade instrument, such as non-hygroscopic KRS-5 windows to prevent damage to the interferometer, a Peltier stabilized DLaTGS detector and a high output ceramic source for maximum sensitivity. Permanent optical alignment is guaranteed by corner cube (retro-reflective) mirrors with auto-alignment for maximum energy. With a resolution of 0.7cm-1 and a S/N greater than 25,000:1.

The FT/IR-4700 has features similar to the FT/IR-4600 but with higher resolution 0.4cm-1 and S/N over 35,000:1, making it ideal for high resolution applications such as gas analysis.

For many routine sample analyses the FT/IR-4000 can be paired with the ATR-PRO ONE single bounce ATR with a choice of prisms including a high throughput monolithic diamond, Germanium (ideal for carbon-black samples) or ZnSe. A choice of clamps with pressure up to 10,000 psi ensures the best sample contact with the crystal.

The newly developed monolithic diamond provides excellent transmission and without any coating or transfer optics has great performance into the far-IR.

For flexible applications a second detector can be added, such as an MCT with automatic exchange (or specify a different beam splitter/detector) for a dedicated system to work in the near-IR or far-IR.

The FT/IR-4000 can be coupled to any of the IRT Series of FTIR microscopes to create a versatile system for both micro and macro FTIR spectroscopy.

The powerful control and analysis software, Spectra Manager™ Suite, is compatible with Windows 7 Pro (32 and 64 bit) and Windows 8.1, providing a customizable user interface for automating routine tasks such as sample identification and quality testing using Quick-Start and QC Compare (with build your own library capability).

KnowItAll® informatics package is included with 12,000 free spectra for life (HaveItAll 250,000 for free evaluation for three months).

Simple Operation

The FT/IR-4000 Series is controlled by Spectra Manager™ Suite cross-platform software. This includes a wide variety of standard functions such as spectra measurement, Quick-Start, QC Compare and quantitative analysis. Additional applications can be added, such as chemometrics (PLS, PCR, CLS etc.). The sample measurement screen can be fully customized according to user requirements and each customized screen and parameters can be saved for different users (User Adaptive Software).

Advanced Measurement Screen of Spectra Manager™


Information such as the instrument status, measurement parameters and the sequence of data acquisition are displayed.

Results Display

Data analysis results such as spectral comparison and sample quantification are displayed and readily available.

Real-Time Monitoring

A real-time data processing function can be used to observe and verify the spectrum during measurements. Spectra stored in thumbnails can also be overlaid with the current spectrum during sample measurements. Self-diagnosis and Validation Self-diagnosis functions allow verification of the current instrument status.


Target peak(s) and/or functional groups can be easily checked by a zoom function.


The measured spectra can be stored as thumbnails within the thumbnail window. The thumbnails can be individually selected and viewed in Spectra view.

Real-Time Data Processing

The data collection/processing sequence can be defined to include several data manipulation commands, activated as the spectral data is collected. The final results after all processing commands are completed are displayed as the final spectrum.
