FT/IR-4X FTIR Spectrometers

The FT/IR-4X 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 temperature controlled 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 high resolution 0.4cm^-1 and a S/N greater than 35,000:1.

For most routine analysis the FT/IR-4X is used with the integrated ATR-PRO 4X 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.

For flexible applications a second detector can be added, such as an MCT or InGaAs with automatic exchange and dedicated options to work from the near- to mid-IR and from mid- to the far-IR.

The FT/IR-4X 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 10 or 11 Pro and Enterprise with user-customizable 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-4X 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).

Sequence

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.

Zoom

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

Thumbnail

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.
