Multi-component Gas Analyser | Gasmet DX-4000 FTIR

Supplier: Thomson Environmental Systems

The GASMET DX series FTIR multi-component gas analyser combines the full capacity of a CEM system with portability.

Price Guide: POA

The unit allows for simultaneous quantification of up to 50 different gas components including H20, CO2, CO, SO2, NO, NO2, N2O, HF, HCL, NH3, VOC’s, Hydrocarbons and Formaldehyde.

One GASMET Gas Analyser replaces many single component analysers providing better mobility, easier and faster setup, high reliability, easier calibration, better selectivity and identification of unknown components

The portable FTIR gas analyser utilises the exceptional speed and specificity of FTIR (Fourier Transform Infrared) spectroscopy and is designed specifically for industrial and environmental applications such as continuos emission monitoring, stack testing, process monitoring, quality control, engine exhaust monitoring and research.

The GASMET DX series can perform simultaneous measurements of both organic and inorganic compounds, as well as analyse hot, wet corrosive gas streams. Measurement capabilities range from low ppm’s up to percent levels. Concentrations of several difference compounds can be measured within seconds. A corrosion resistance sample cell is heated up to temperatures of 180°C, eliminating the additional need for complicated sample dilution or water vapour removal systems. The GASMET DX offers excellent calibration stability, simple operation and low cost maintenance.

An integral part of the system is the Calcmet-software.  Calcmet analyses the sample spectrum, operate the GASMET and controls automated sampling system units. Using Calcmet cross interference effects are compensated for and analysis accuracy is maintained when analysing complex gas mixtures with spectral overlapping.
