ODOUR LABORATORY TESTING
At Silsoe Odours, we operate a leading independent odour laboratory, based in Bedfordshire. Our laboratory was the first in the UK to achieve UKAS accreditation. We continue to uphold these industry-leading quality standards. Our range of odour testing services is designed to help you understand nuisance odours, with both quantitative and qualitative services available. Our goal is to provide you with the scientific data you need to differentiate odour sources and understand the impact they have on the local environment.OUR ACCREDITATIONS
Our team of odour specialists not only provide a fully integrated odour service, but also a lab-only standalone service. So, regardless of your in-house capabilities, we can support your odour assessment and management requirements at every level. This means that you can commission us for a complete odour assessment, sampling and testing assignment, as well as simply sending us your odour samples for testing.
If you are in the business of taking odour samples in-house, it’s important that you comply with the requirements of European Standard BSEN13725:2022. Providing your sampling methodology complies with the relevant olfactometry standards, we can analyse your samples.
At Silsoe Odours, we use a process of gas chromatography-mass spectrometry (GCMS) to analyse the chemical structure of an odour sample. This type of odour testing provides our customers with an objective scientific result. It details the individual compounds contained within the odour sample, as well as its concentration levels. This information can be used to identify which odours are problematic for an operator, and in the creation of an effective odour management plan.
ODOUR DETECTION THRESHOLD
By testing the odour detection threshold of a compound, we are able to give a numerical value to its odour. This is often useful for odour abatement equipment manufacturers. By understanding the odour detection threshold of each compound in a given process, you can easily exclude emissions of compounds which fall below that threshold when designing new odour abatement equipment. As with all our testing, we conduct odour detection threshold testing according to the European Standard EN13725 in our UKAS-accredited odour laboratory.
Odour intensity testing is an olfactometric testing service which provides a qualitative scale to rank the perceived strength of an odour; from very faint to extremely strong. Odour samples are presented to and assessed by our human panel of odour assessors. The odour panel comprises six specially selected, screened and trained odour assessors, who are continually tested and calibrated to ensure an objective result. Our customers often find the results of odour intensity testing useful for safe space planning and validating the results of dispersion modelling.
Odour characterisation is a subjective odour testing service, which provides a description of an odour at just above the odour detection level. As with odour intensity testing, odour characterisation is completed by the Silsoe Odours odour panel. Odour characterisation is often helpful for operators receiving odour complaints, to confirm the validity of those complaints. It is also useful in the development of odour management planning and in satisfying the regulator

We have worked with Silsoe odours for many years, and have always been impressed with their friendly practical approach, technical expertise and flexibility. We look forward to working with Silsoe Odours again in the future and would not hesitate to recommend their services.
Silsoe Odours are invaluable to me as a partner for testing odour samples. I use their laboratory services, on average, several times each month, for many of my clients. They are a great source of expertise and allow me to offer clients an integrated odour consultancy experience, without the associated overhead and resourcing costs of operating my own laboratory. They understand both my needs as an independent environmental consultant, and those of my clients – whether utilities or multi-national operators. The flexibility and ease of working with Silsoe Odours is hugely valuable. I don’t hesitate to recommend their services.
