FT-IR 6000-series

With a 28 degree Michelson interferometer and corner-cube mirrors for optical precision and designed for absolute flexibility

In its ‘standard’ configuration it has an extensive range of source, beam splitter and detector options from near-IR to mid-IR to far-IR measurements.

Customize for virtually any experimental requirement

The real advantage of the FT/IR-6000 Series, is not just the uncompromising design and high optical throughput, but also the ability to customize them for virtually any experimental requirement.

  • Nitrogen Purge and Evacuation

    A multi-zone N2 purge system is standard to minimize the interference from environmental gases and vapors on the sample spectrum (CO2 and H20 elimination algorithms are also provided).  The interferometer, sample chamber and detector areas can all be independently evacuated (useful for fast sample loading) to completely eliminate CO2 and H20 for the most sensitive sample measurements and as the moving mirror does not really on an air-bearing the vacuum can easily be maintained. The FT/IR-6000 FTIR spectrometer can also be used in a combination of vacuum and purge for even faster sample turn-around.
  • Emission Ports and Light Introduction

    The FT/IR-6000 has several options for emission port optics with a range of window materials for measurement of external light sources. These can be coupled with customizable collection optics to focus a range of sizes and power outputs of light sources into the interferometer.
  • Rapid Scan and Step Scan

    Rapid Scan (optional on FT/IR-6600 and 6700, standard on the 6800) offers spectral collection up to 20Hz (50msecs).
    Step-scan interferometers (optional on all 6000 FTIR instruments) coupled with matching high speed detectors offers two different spectral collection rates at either 1 millisecond (1000 Hz) or 10 nanoseconds (100MHz).

Powerful Data Analysis

The FT/IR-6000 Series is controlled by Spectra Manager™ cross-platform software. Spectra Manager™ includes various capabilities including Spectra measurement, Quick-Start, spectral comparison and quantitative analysis as standard functions. The sample measurement screen can be customized according to user requirements and the customized screen and parameters can be saved for future use (User Adaptive Software capability).

Advanced Measurement Screen of Spectra Manager

Measurement parameters and data acquisition/spectral processing sequence 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 verify the current spectrum during measurements. Spectra stored in thumbnails can also be overlaid with the current spectrum during sample measurements.

Target peak and functional group information can be easily checked using the 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

Before start of a sample measurement, the data processing procedures can be verified by checking the results of real-time data processing in a preview window.

FTIR Spectrometers System Features


The interferometer is manufactured as a solid cast aluminum block  and is completely sealed. The FT/IR-4000 uses a 45 deg Michelson interferometer and the FT/IR-6000 uses a 28 degree Michelson interferometer. A near frictionless bearing (without the need for a gas supply) supports the moving mirror which is driven by a ‘voice coil’ for accurate vibration free movement.  Laser tracking of the moving mirror is made using Accutrac™ with the latest in digital signal processing. The standard KRS-5 windows prevent hygroscopic damage often seen with KBr windows used on some products.

Corner-Cube Mirrors

Corner cube mirrors automatically correct for any light path deviation, providing excellent optical stability at all times. Eliminating the need for dynamic alignment.

  • Purgeable Optics

    All models include a fully sealed and desiccated interferometer chamber. In addition, an integrated purge for the optical system is included as standard.
  • Excellent S/N Ratio

    The highly stable interferometer with high intensity two-stage light source   offers optimum signal-to-noise performance starting at 28,000:1 and up to 55,000:1 (under standardized conditions).
  • High Sensitivity Electrically Cooled DLaTGS Detector

    A highly sensitive and stable DLATGS detector is standard for all instruments. The DLATGS detector element is temperature-controlled using the Peltier effect.
  • Additional Detectors

    Many optional detectors cover the range from 25,000 to 5 cm-1 and include several LN2 cooled MCT detectors for wide, narrow and mid band, Other include SiPD, InGaAs, Bolometer, etc.
  • Wavenumber Extension

    The working range can be extended from the visible to far-IR by switching various optical components, such as source, windows, beam splitter and detector.
  • Vibration-Free Optical Bench

    A specially designed vibration-proof mounting of the optical bench completely eliminates interference from external vibrations.
  • GxP Support

    For laboratories compliant with GxP regulations, an instrument validation routine is provided as standard to verify instrument performance compliant with ASTM, EP, and JP procedures.
  • Microscope/IR Imaging

    The IRT-1000, 5000 or 7000 infrared microscope models can be easily interfaced to any FT/IR-4000 or FT/IR-6000 instrument.

Genetec is a member of the same family of companies as Kovalent. Both companies share the same set of values and are in many ways integrated with each other. The main difference between the two companies are their products. Kovalent is involved in system solutions including instrumentation and Genetec is mainly working with consumables. The focus of Genetec is chromatography accessories. You are welcome to visit their state of the art web shop: genetec.se
