WHAT IS ODOUR CONCENTRATION TESTING?

Odour concentration testing is the core odour laboratory testing service we offer at Silsoe Odours. From our UKAS-accredited odour laboratory in Bedfordshire, we are able to determine the concentration of an odour in an objective way, using the process of olfactometry. This process allows us to give an odour source an objective number, which is useful in the calculation of emissions 

Silsoe Odours Ltd has over two decades of experience in odour analysis and management. Our team of odour scientists can provide the data and guidance you need to assess whether odour pollution is a problem, and implement effective odour controls where necessary.

We use the odour concentration measurements that comply with the European Standard BSEN13725:2003

ODOUR LABORATORY TESTING

Odour Measurements – What is Olfactometry?

This is a process used to measure odour concentration. Olfactometry determines concentration of an odour in an objective way.  The intensity, quality and hedonic tone are purely subjective and emotional responses.

The Olfactometer.

The olfactory organ (the human nose!) is the only sensor of odour, and the process of olfactometry enables us to harness this in an objective way. We make use of an olfactometer – a device that dilutes an odorous sample to a known concentration, for presentation to our specialist odour panel. The Silsoe Odours odour panel comprises six specially selected, screened and trained odour assessors. They participate in a ‘forced choice’ progression of odour assessment, until a resulting odour concentration is established. This concentration is expressed in units of European Odour Unit per cubic meter (ouE/m3).

All our odour assessors are selected and continually efficacy-checked according to the requirements of BSEN13725:2003.

ISO 17025 Accreditation maintained

Silsoe Odours laboratory was the first in the UK to gain UKAS accreditation for odour concentration measurements by dynamic olfactometry to BS EN 13725:2003. Our surveillance visit in 2017 was successful in maintaining our current accredited status for a further 12 months.

We were pleased to receive the following feedback from our assessors:

“Once again, the way in which the activities witnessed were carried out, the knowledge of the staff employed and the performance in the external proficiency scheme…gives confidence in data produced.”
