CR4000 FTIR Gas Analyzer

Multicomponent FTIR Gas Analyzer
Gasmet In-lab Series includes quantitative multicomponent
gas analyzers for laboratory research applications. The
Gasmet CR4000 incorporates a Fourier transform infrared,
FTIR spectrometer, a temperature controlled sample cell, and
signal processing electronics. Liquid nitrogen cooled MCT
detector has the highest performance available.

Spectrometer
Resolution:

Recommended 8 cm-1 or 4 cm-1

Scan frequency:

10 scans / s or faster

Detector:

Liquid N2 cooled MCT

The Gasmet CR4000 is designed for highest sensitivity and
speed. It is an ideal tool for example for emissions
measurements, catalyst research applications, or to measure
any compounds in wet corrosive gas mixtures. The longer path
lengths of the sample cell provide low detection limits. The
gold coated sample cell can be heated up to 180 ºC.
