The FT/IR-6000 FTIR spectrometer uses a 28 deg Michelson interferometer with corner-cube mirrors, the moving mirror is supported on a ‘near frictionless’ mechanical bearing (that does not require air) and driven by an electromagnetic coil. The moving-mirror is monitored using a HeNe laser with Accutrac digital signal processing (DSP) for the highest positional accuracy.

Wavelength Range

The standard spectrometer uses Ge/KBr beam-splitter with KRS-5 windows and a DLaTGS detector with KRS-5 window, spectral range 7,800 to 350 cm-1. There are a wide range of options to change the spectral range from 25,000 to 10 cm-1, including fully automated beam-splitter and window exchange for unattended operation. With the widest choice of materials, a wide spectral range cna be covered using a minimum number of components including a new broad-band beam splitter, window and detector combination covering the Mid-IR to Far-IR

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 included).  The interferometer, sample chamber and detector areas can all be independently evacuated in a full or partial vacuum instrument  (useful for fast sample loading) to completely eliminate CO2 and H20 for the most sensitive sample measurements and as the moving mirror does not rely on an air-bearing, the vacuum can easily be maintained.

Emission Ports and Light Introduction

The FT/IR-6000 has several options for optical ports with a range of window materials for measurement of external sources of light and black body devices..

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 (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). Using Amplitude or Phase modulation and Time Resolved with photo-acoustic detection.

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.
