Odour surveys involve either assessment of odours around a site by sniff testing or direct measurement of odours from their source by olfactometry or odorous VOC speciation. We offer a full range of odour measurement and analysis services including UKAS/MCERTS accredited techniques which are required for permitted industrial and waste sites (e.g. odour, hydrogen sulphide, ammonia, etc) as well as smoke testing and building leakagetesting.

Odour impact assessments may be required for planning of new industrial facilities or residential developments near existing odorous facilities, permitting, capital planning, or investigation of odour complaints and nuisance. We offer a full range of services compliant with existing guidelines which can be specifically tailored to our client’s needs, from simple risk assessments to more detailed quantitative studies.

Odour analysis is required when assessing the potential impact of odours and to support design of odour control systems. We offer a full range of analysis services from our laboratories in Bristol and Northwich which include UKAS accredited olfactometry to BSEN13725, hedonic tone analysis, character analysis, VOC speciation, GC-sniffing. We can also test the sensitivity of your own monitoring to staff to odour using our accredited acuity testing procedures.

Odour dispersion modelling is a specialist tool to assess odour impact, often required as part of a planning or permit application. We are specialists in this area having introduced the odour impact standards that are currently used in the UK. We can offer modelling by AERMOD or CALPUFF using emission estimates from our extensive emission database or site specific data obtained by odour survey.

Our innovative Ortelium software provides a means for site operators to continuously collect and analyse data for real time management of odour issues and complaint investigation. Key features of the platform include the ability to forecast odour impact risk, validate odour complaints, and ensure that odour control systems are operating in accordance with design.

Control of odours can be achieved using a range of techniques which include minimising odours at source, good housekeeping, containment/collection/ treatment, enhancement of dispersion using chimneys or stacks.
As independent odour specialists, we have expert knowledge in all the available techniques including odour treatment technology such as carbon filters, chemical scrubbing, biological treatment, and incineration. We can support our clients to prepare effective Odour Management Plans and undertake flow and load surveys to help design effective solutions.

Dust and bioaerosol monitoring is a common requirement in industrial permits and may be required during planning, commissioning testing or for nuisance investigations. We can provide ambient dust monitoring in accordance with MDMS and IOSH standards as well as MCERTS accredited bioaerosol monitoring in accordance with section 5 of Environment Agency M9.

Stay up to date! We offer you and your employees regular workshops, seminars, and individual training sessions on all issues relating to the measurement and evaluation of odours.

All our sensory or molecular odour tests help to answer certain questions.

Once we know what questions you need answered, we can identify the most appropriate techniques.

Olfasense ensures best possible analysis results by combining standardised measurement – for traceable and reproducible results – with individualised sampling

The processes, methods and target parameters of our sensory odour analysis are diverse.

Olfasense is in a unique position to have both sensory and molecular odour analysis capabilities in-house.

Odour measurement requires the human nose as tester. This means that one of the biggest challenges is getting valid test results with high repeatability.
