Multicomponent FTIR Gas Analyzer
Gasmet In-lab Series includes quantitative multicomponent gas analyzers for laboratory research applications. The Gasmet CR2000 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.
The Gasmet CR2000 is designed for speed and reliability. It is an ideal tool for example for motor exhaust measurements, catalyst research applications, pyrolysis research, or to measure any compounds in wet corrosive gas mixtures. The small volume of the sample cell provides short response times. The gold-coated sample cell can be heated up to 180 ºC.
CR-models scanning and analysis speed can be configured according to customers need.
