Is the analysis of NH3 and H2S molecules enough to qualify and quantify odors (odours)?

No, the analysis of H2S (hydrogen sulfide) and NH3 (ammonia) molecules is not sufficient to assess all odors (odours) present in an environment. Although these molecules are commonly analyzed using electrochemical sensors, they only represent a fraction of the odor (odour) compounds. Hydrogen sulfide and ammonia are indeed important components of certain odor (odour) nuisances, but many other chemical compounds are responsible for varied and complex odors, such as aldehydes, volatile fatty acids, and mercaptans, which are not detected by these traditional technologies. This is precisely what the MOX (Metal Oxide Semiconductor) sensors used in Ellona devices, such as the WT1 Lite, the WT1 Pro (specifically designed for outdoor use), and the POD2 (adapted for indoor environments), are capable of detecting.

How to measure, identify, and precisely locate odors (odours) outdoors?

Odors (odours) are measured, identified, and precisely located by deploying devices either at the source (technical facilities, industrial sites, etc.) or on the periphery of sites to monitor dispersion and assess the impact of olfactory nuisances.

Ellona’s devices, such as the  WT1 Pro  and  WT1 Lite ,do more than just measure odor (odour) levels. Thanks to a combination of MOS sensors and advanced data processing based on multivariate statistics and artificial intelligence, our sensors can accurately identify the nature and sources of olfactory nuisances. The WT1 Pro, designed for confined sources, is particularly well-suited for this task, while the WT1 Lite is dedicated to monitoring the periphery of sites, tracking odor (odour) dispersion in the environment.

Ellona also relies on several recognized methodologies to identify odor (odour) sources:

  • source observation,
  • clustering, the FISOL methodology,
  • and dynamic olfactometry (EN 13725), which is only possible with the WT1 Pro.

These approaches analyze nuisances based on their temporal recurrence, intensity, frequency, and duration. All collected data is integrated into atmospheric dispersion models that factor in meteorological conditions (wind direction and speed, temperature, humidity, etc.), allowing for a comprehensive analysis of odor (odour) propagation and the optimization of nuisance reduction strategies.
