FTIR (Fourier Transform Infrared)-analysis: Gasmet DX 4040

As from june 2014 we are using the FTIR -technique, which enables us to carry out a real-time analysis at any location. The reliable FTIR-technique is based on the traditional infrared spectroscopy technique which is being used in laboratories all over the world for decades.

Advantages of the FTIR-technique:

Ammonia analysis: measured spectrum and found concentrations

Excluding false-positive results by comparing (by overlay) the measured ammonia spectrum (in black) with the reference spectrum (in red). Result: perfect match


On request the measurement results including the spectra of interest are reported by us.

Remote monitoring

By the use of special Gasmet software, remote monitoring of the measurement results (including the spectra of interest), is possible.

Basis for the Risk Assessment and Evaluation (In Dutch) RI & E)

The extensive and reliable FTIR-measurement results form an excellent basis for the RI & E. The FTIR-technique enables us to analyse hundreds of gases and vapours in a range from very low to high concentrations. In addition, by the use of the Nist Reference Library, we are able to identify > 5000 substances. However, when using the Nist list, quantification of the found substances is not possible. With this technique it is not nescessary to take additional air samples.

Test field measurement methods

We also use the FTIR-technique to check our traditional (tubes and sensors), or GDA-2 technique. In the past we had to take (costly) air samples to check our measurement techniques.

Ethylene oxide (EtO)

The FTIR-technique is recommended by the German Labour Inspectorate Authorities in relation to the German standard TRGS (technical rules for hazardous substances) 513 which applies for EtO sterilization.
