Ambient Air Analysis with FTIR

Gasmet Technologies (Finland) is a manufacturer of FTIR gas analyzers for demanding industrial gas monitoring applications. The latest addition to the Gasmet product family is the Gasmet Dx-4030, which is the first truly portable FTIR gas analyzer on the market.
With Gasmet Dx-4030 no sample preparation is needed; the sample gas is drawn into the analyzer with a built-in pump and a particle filter. Unlikely some other portable FTIR`s, the Gasmet Dx-4030 does not require to pre-concentrate the sample with a thermal desorption tube. This ensures nearly instantaneous response times.
The Gasmet Dx-4030 is able to monitor simultaneously concentrations of up to 25 compounds in surrounding air. The user has also the option to transfer the measurement data to a laptop, where it can be further analyzed with the help of an extensive spectral library. For example, previously unknown / non-calibrated compounds can be identified based on their unique IR – spectrum.

GASMET Dx-4030 FEATURES:
• Fourier Transform Infrared Spectroscopy (FTIR) analysis
º Identification of both organic & inorganic compounds
º Multi-compound analysis as standard (max. 25 compounds analyzed
simultaneously with Calcmet Lite)
