Odour emission measurement and odour impact assessment are a key factor in the approval and planning of many industrial and agricultural facilities. Which can mean nothing less than securing the operation of your plant. In order to eliminate environmental ‘nuisance’ odours, we analyse the sources of emissions at various point sources or area sources of your plant. On this basis, we evaluate the pathways and the odour impact. Our expertise: 4 accredited odour laboratories and a state-of-the-art GC-Sniffing-MS laboratory for molecular odour evaluation. More than 6500 realized odour projects with our own mobile laboratory worldwide. Our claim: Sensory and molecular odour analyses at the highest level – including the accurate selection of panelists, specific training, and the monitoring of precise data.

Our company was faced with a difficult task to propose a new odour limit in a non EU country in order to change an emission permit to one where we no longer needed to measure dozens of emissions which were non-hazardous, costly to analyze and could not be controlled. Some said that the task was impossible and we should not even try. We were pointed by some industry colleagues to Olfasense and after exchanging just a few emails about work Olfasense does and their international experience, we knew we had a right partner for this job.Annamarie Velic, Sustainability Manager at large retail company

FAQs - Frequently asked questions about odour testing
How is odour measured?
All recognized odour measurement methods work with human noses. For this purpose, panellists are used whose olfactory ability has been tested in advance. These panellists assess the odour on the basis of samples taken at the source, or directly in the ambient air around odour-emitting plants.
Can I measure odours myself with one of your devices?
Our devices are designed to perform standardized tests using the human sense of smell. For this purpose, a sample of the odour is first taken at the source. Our devices prepare the samples for the trained panellists to measure the odour. At the moment it is not yet possible to measure the type and concentration of odour exclusively with instruments. Even a measurement with sensors (formerly electronic noses), which can measure odour within certain limits, must always be traced back or calibrated to the human sense of smell. In this way, specific odours can be mapped as well as possible to human perception.
Is there a technology that can replace the human sense of smell, similar to an “electronic nose”?
No. Often smells consist of many different chemical substances. Not every substance is necessarily relevant for odour perception. Studies show that the human nose can (theoretically) distinguish over 1,000,000,000,000 different smells. Instrumental measurement systems do not yet provide this performance. Due to the great differences between technological measurement systems and the biological sense of smell, there is currently no technology that can replace the highly complex human sense of smell. There are some applications, such as process monitoring, instrumental measurement systems can be used for. However, also for those applications, measurements have to be traced back or calibrated to the human sense of smell. In this way, specific smells can be linked as well as possible to human perception.
