Air, odour and emissions
Odour laboratory for accredited odour measurement, analysis and consultancy
Measure and analyse industrial odour emissions with accredited laboratory testing and olfactometer.
The Odour Laboratory supports companies that must measure and document odour emissions from industrial activities, production sites, restaurants or technical installations. The need typically arises when companies must demonstrate compliance with environmental approval, respond to authority requirements or investigate the origin and strength of odours.
Documentation and management of odour emissions
Odour emissions can lead to complaints from surrounding communities and may require documented measurements to confirm emission levels or assess mitigation measures. By measurement, analysis and consultancy, the laboratory provides a documented basis for dialogue with authorities, environmental reporting and evaluation of odour control measures. The service is part of our catalogue within measurements of air, odour and emissions.
Target group and benefits
Supporting industrial companies and facility operators that must measure and document odour emissions
The odour laboratory supports companies, plant operators and organisations that need to assess airborne odour emissions from operational activities. Typical users work with environmental documentation or compliance with environmental permits. The laboratory can measure odour emissions to document compliance with limit values, investigate reported odour nuisance or assess changes in emissions following technical modifications to production or process systems.
Use of measurement results in practice
The results are used in environmental reporting, technical evaluations and dialogue with authorities regarding emission levels or operating conditions. The laboratory also performs customised analyses when companies need to investigate odour from specific materials.
Discuss odour measurement needs with our specialists
Contact the odour laboratory to discuss sampling, measurement and analysis of odour emissions and determine the appropriate testing approach for your facility.
Facility setup
Configure sampling procedures, laboratory analysis and panel testing to evaluate odour emissions from different sources and materials.
Source sampling of odour emissions
Air samples are collected from emission sources such as stacks or other defined release points. The samples are captured in odour bags that preserve the air's composition until analysis.
Controlled dilution and presentation of samples
Collected samples are connected to the olfactometer, where the sample air is diluted with clean air in a controlled sequence before being presented to the odour panel. The instrument performs an automated series of dilutions.
Panel-based odour detection procedure
During analysis, panellists are exposed to a sequence of diluted samples and indicate when the odour becomes detectable. The dilution level at detection is used to determine the odour concentration of the sample.
Odour character assessment
Panellists may also describe the perceived odour character, such as rotten, chemical or sweet, providing additional context for interpretation of emission sources.
