TO evolution laboratories pass EN 13725 interlaboratory comparison without exception

We have been informed by happy olfactometer clients that all TO evolution laboratories that participated in the 2016 Interlaboratory Comparison for Olfactometry have passed the proficiency test with excellent results. Here are testimonials of just two of them:

“We are very satisfied with our new olfactometer, the quality of the equipment and the interfaces allowed us to get used to it quickly. A few weeks after its installation, we were able to participate and pass our interlaboratory tests.
The TO evolution olfactometer and the services offered by Olfasense for the maintenance and calibration of this equipment enable us to offer our customers a high quality service (accuracy, repeatability and speed of analysis) to the highest international standards. We particularly appreciated the possibility of shipping Olfasense our dilution unit for the annual accredited calibration. By planning this operation, it did not affect the productivity of the laboratory.
We have had the pleasure to obtain our accreditation according to ISO 17025 with our new equipment which has met all the expectations of the evaluators of the BELAC (design, calibration, data protection, stability, precision, reliability …).”

“Odournet UK Ltd purchased two TO evolution olfactometers in 2015 and 2016, from Olfasense GmbH. Olfasense have provided a great service, with efficient supply and installation of our olfactometers and knowledgeable, friendly support whenever we’ve needed it. We were quickly able to integrate these olfactometers into our long-standing UKAS accreditation.
We have always been very confident in this technology, but have recently received the results of the worldwide interlaboratory comparison that we participated in, earlier in 2016, and are exceptionally happy with our achievement using the TO evolution olfactometers. We were within the top 3 places, for accuracy, out of 36 participating similar odour labs!”

We are sending out our heartiest congratulations to all the hard working laboratory teams.

With two own accredited laboratories, we fully understand the challenges to meet the constantly growing requirements for quality management in odour laboratories.

As manufacturer of the TO evolution olfactometer, this proof of accuracy and traceability makes us obviously also very proud – and confident that the TO evolution olfactometer allows for odour testing services to the highest quality standards.
