Learn how to collect, store and send odour samples safely for accurate laboratory testing. This guide explains best practice odour sampling methods and how to ensure reliable, UKAS-accredited testing results.
Silsoe Odours has helped shape odour science in Europe for decades. Our Director, Robert Sneath, helped develop EN 13725:2022, the European standard for odour measurement. This blog explains what the standard covers, why it matters, and how UKAS-accredited testing ensures reliable results.
Odours are subjective, varying from person to person. This makes them hard to measure. But objective odour measurement is possible. The key is using trained assessors, standardised methods, and accredited lab testing. UKAS accreditation to BS EN 13725:2022 ensures results are reliable and accurate. This makes odour data useful for planning, permitting, and environmental investigations.
At Silsoe Odours, we carefully select, screen and train our team of odour panel members, or “sniffers”, to conduct odour services including odour testing (including odour characterisation) and sniff surveys. Our rigorous process means you can rely on the accuracy and reliability of all our results. As part of our ongoing training, sniffers participate in…

Many industries have operational processes that create odour. For example, wastewater treatment plants, composting facilities, rendering plants, agriculture and food processing. In all these cases, effective odour control is important for compliance with environmental regulations, and the well-being of the community. A good way to reduce the impact of these odours is to treat them…

AN EFFECTIVE STACK REDUCES ODOUR IMPACT Odour emissions can pose a risk to the well-being of nearby communities. One way to mitigate this risk is to install a stack that helps emissions to disperse before reaching a human nose. Designing an effective stack is crucial as it can be a costly process. However, installing…

Olfactometry is the science of measuring odour. Using trained human odour assessors and specialist laboratory equipment, dynamic olfactometry enables us to quantify odour concentration with precision and reliability. Widely used to investigate nuisance complaints, assess environmental impact and evaluate control measures, it remains the gold standard for odour measurement. In this guide, we explain how olfactometry works, why human assessors are essential, and how we ensure accuracy and safety throughout the process.
Selecting the right odour consultant is critical for accurate odour measurement, compliance, planning and operational efficiency. Learn what to look for in experience, accreditation and Safe Contractor status.

In 2022, a new revision of EN17628 reached publication. This standard aims to reduce atmospheric emissions, including methane, ammonia and other harmful gases. As a result, Silsoe Odours is currently supporting several clients with thermal imaging projects to detect gas leakage. The new standard is titled “BS EN 17628:2022 Fugitive and diffuse emissions of common…
