    * formerly Odournet
  • “With Olfasense* we have been maintaining a strong and reliable long term supplier relationship for over 7 years. They have proven to be responsive to our needs by developing innovative and bespoke test designs in the field of deodorant testing.” 

    Beiersdorf AG

    * formerly Odournet
  • “FORCE Technology has worked with olfactometry for 30 years, and for the last two years used a TO8 Olfactometer from Olfasense* as our only olfactometer. We are very satisfied with the function of the TO8, which is easy to handle and have good report facilities.“

    Arne Oxböl, Project engineer at FORCE Technology

    * formerly Odournet
  • “We are using products from Olfasense* for many years now and also take advantage of the regular calibration service. We are very satisfied with both, product and service, and were promptly served at each request. In addition to the olfactory tools, we commissioned GC-MS analysis and specific testing, and both services have been done to our utmost satisfaction at all time. Thank you for that. 

    Dipl.-Ing. Holger Eich, Development Ventilation, Neff GmbH

    * formerly Odournet
  • “Frans Vossen from Olfasense* came to HMEL’s Guru Gobind Singh Refinery in Punjab, India to help us understand and deal with odor complaints from the surrounding villages. Frans left us with severable clear action items to reduce odors. As a result of his work, we have reduced odor complaints by over 50%. We searched the world to find Frans. He is the leader in the field of odor identification and elimination.“

    Martin Hawkins, COO, HMEL

    * formerly Odournet
  • “​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

    * formerly Odournet
  • “Olfasense* has provided training in the use of their olfactometer and calibration of the equipment, allowing optimal equipment performance and reliable measurement results.“

    Sayda Almendra Marmolejo Correa, CIATEC A.C.

    * formerly Odournet
  • “​During the work on the odour research, Olfasense employees showed high professionalism and focus on the results. It was a pleasure to work with a team of highly skilled specialists.“

    ​Market-leading Russian tobacco company

    * formerly Odournet
  • “We have used Olfasense* for service and calibration twice and appreciate the fast and reliabte service. Our olfactometer was out of service for only six days. lt was easy to arrange with Olfasense calibration department. We have a good contact with Olfasense’s technicians and get quick answers, when we have technical questions.“

    Arne Oxböl, Project engineer at FORCE Technology

    * formerly Odournet
  • “Olfasense* has provided technical support since 2000, including training, equipment calibration and technical advice. This has allowed us to apply olfactometry in the central region of Mexico to develop odour maps in cities with these problems, identifying the sources that cause them, the existing odour concentration and impact on the population, which has allowed to implement corrective measures.“

    Sayda Almendra Marmolejo Correa, CIATEC A.C.

    * formerly Odournet
  • “We carefully selected Olfasense* as a highly qualified and specialized consultant to support us in analyzing the odor/off-gases of a production plant in China. Apart from professionalism I consider easy access, flexibility and interactive communication on execution and reporting as the key elements that made this project successful.“

    ​Ron Thiecke, Director Safety, Health and Environment, ​​DSM Sinochem

    * formerly Odournet
  • “We would like to thank the Olfasense* team for their help, advice and trainings from the beginning of foundation of our odour laboratory up to now. The whole process was simple and trouble-free, resulting in having an effectively functioning odour laboratory. Thanks for the excellent and fast service and I look forward to working with Olfasense for the foreseeable future.“

    ​Algirdas Keblas, National Public Health Surveillance Laboratory

    * formerly Odournet
  • “We have had an olfactometer device since 2012 and we haven’t experienced any technical problem until now. We have only had a little issue with the software of the instrument but Olfasense’s* authorized staff was really helpful to solve it.“

    ​Sercan Soytaş, ARTEK

    * formerly Odournet
  • “Based on your olfactory data we have already gained good quantitative insights into the key (off) odour drivers so your data turned out to be very actionable for us. Thanks for the good work.“

    Dr Eduard P.P.A. Derks, Senior Scientist Analytics & Statistics, DSM Resolve

    * formerly Odournet
  • “We were among the very first who introduced olfactometers to the local air quality assessment work in Russia by purchasing the piece of equipment at Olfasense*. With Olfasense's highly professional and friendly methodological and technical support we learned the technique and have been applying it ever since. We can attest that the whole cycle of our cooperation has been effective and pleasant.“

    ​SRI Atmosphere JSC

    * formerly Odournet
  • “Over the years, Olfasense* has demonstrated to be a reliable supplier of Olfactometry services for us. We are satisfied with their professional non-defensive open attitude, to listen to our concerns and needs and co-operate to achieve the best possible experimental setup. The generated data are in a agreed format (flawless!), and delivered in time.“

    Peter Degenhart, Lead Scientist at one of the world's largest polypropylene producers

    * formerly Odournet
  • “For many years we have analysed odour with an olfactometer from Olfasense*. The equipment is very reliable, and we have never been in a position where it was not possible to perform the analyses planned. Only once we have experienced an error to the olfactometer. The error was discovered during in-house inspection of the olfactometer on the day before a large series of analyses – with quick and qualified help from the service department of Olfasense, the series of analyses could be performed as planned and within time limit established by the European Standard for odour determination by dynamic olfactometry. Excellent Service!“

    Ole Pontoppidan, Danish Meat Research Institute

    * formerly Odournet
  • “You are looking for a company with great experience, high flexibility and with an highly motivated team helping you to find everything around odor which can be measured? With the great experience and human panel, Olfasense was helping us to demonstrate the measurable odor control performance from our new material for human hygiene products. In a second step they were also helping us to develop a short and easy method to demonstrate the odor control capability in an visual test which we can show to our customers in less than 5 minutes. All this work was done in a very short time fitting to our thigh project realization. With the help from Olfasense we have been able to smoothly implement our new product into the market. We will definitely consult the great Olfasense team again, when we would need an similar support at future.“

Network

Olfasense started small and has achieved growth and success thanks to its partners, who help make us what we are today. We’ve always looked for opportunities to share knowledge and work in partnership, and we do this right across our portfolio. We’re proud of our strong ties with partners from academia and both private and public sectors.

St. Croix Sensory is the leading odour laboratory in North America with international recognition in the field of odour measurement. Since 1980, St. Croix Sensory’s laboratory has specialized in sensory testing of environmental samples, commercial products and materials. In addition, St. Croix Sensory manufactures and markets state-of-the-art odour sampling and measurement equipment. St.Croix is Olfasense’s exclusive distributor in the North American market for Olfasense’s extensive portfolio of odour measurement equipment, including the new TO evolution olfactometers and Ortelium® .
Olfasense is proud to be a certified sales and research partner of the GC-IMS specialist G.A.S. Gesellschaft für analytische Sensorsysteme mbH (G.A.S.). A leader in GC-IMS technology,G.A.S. manufactures gas analysers for trace detection. Its instruments are admired for their speed and sensitivity – they provide analytical results in the lower ppbv-range within just a few seconds – as well as for their economical pricing. And, as always, we are looking to the future. Together with G.A.S., we’re working to develop this powerful analytical method even further – so watch this space.
Ecometrika is Olfasense’s exclusive Ortelium® sales partner in Chile. As odour regulations are developed in Latin America, input from established experts in the field is critical. A leading provider of odour consultancy in Chile and the rest of South America, and a longstanding Olfasense partner, Ecometrika is well placed to make a difference.
Based in Hamburg, Cosmacon GmbH is an innovative, results-driven company providing practical solutions for the cosmetic development industry. Rainer Kroepke, its founder and CEO, is considered one of the leading independent cosmetic developers in Germany. With over 25 years of practical experience in cosmetic development and more than 350 patents to his name, he founded the company RK Cosmetic Consulting in 2013, which was transferred to Cosmacon GmbH in 2016. Our partnership work in this area means that clients benefit from our companies’ complementary expertise in the overlapping fields of cosmetics and sensory testing. We not only offer support in the development of cosmetics but also in the sensory and molecular measurement of odours in the cosmetic products or raw materials.
Olfasense’s partnership with Kuiper & Burger Engineering and Consultancy ensures that both organisations can provide a comprehensive service to address our clients’ environmental nuisance issues. Specialising in environmental studies in the fields of environment, safety and spatial planning, Kuiper & Burger works with many different industries, including bulk storage and handling, waste handling, energy production and chemical and other specialised industries.

More About Us

We've started small but we've always aimed high. Find out more about our history, our scopes of accreditation, and our involvement in relevant odour working and standardisation groups.

Offering accredited services to the highest possible quality standards

Olfasense has always aimed to be an innovator, so it is fitting that we pioneered ISO 17025 accreditation – the main and most important standard for calibration and testing laboratories globally. We obtained our first (ISO 17025) accreditation certificate on 28 September 1993 for our Amsterdam laboratory.

We now run two testing laboratories for olfactometry according to the European Olfactometry Standard EN 13725, in Germany and the Netherlands. In addition, the German laboratory is accredited for the VDA 270 measurement method.

What’s more, our manufacturing and testing process of Nalophan gas sample bags is accredited under ISO 17025.

In addition, Olfasense is accredited to carry out proficiency tests for the measurement methods EN 13725 and VDA 270 according to ISO 17043.
