WE QUANTIFY THE UNMEASURABLE.
EN 13725 dynamic olfactometry. Odor becomes a number, not an opinion.

THE STANDARD THAT CHANGES THE ARGUMENT

Under EN 13725:2022, odor stops being a matter of personal sensitivity and becomes a measured quantity, expressed in European odor units per cubic meter. That single shift is what moves a case from he said, she said to evidence.

INSIDE THE LABORATORY

Our dynamic dilution olfactometer presents each sample to a panel of assessors screened against the n butanol reference, using a forced choice method that removes guessing. From their responses we determine the odor concentration and the detection threshold with laboratory grade repeatability.

BEYOND THE THRESHOLD

Concentration is only the beginning. We characterize the full profile that regulators and courts ask about. Chemical identity through GC MS O, pairing gas chromatography with the human nose to name the compounds that matter. Intensity across the concentration range. Hedonic tone, how pleasant or offensive the odor is judged to be. Character and persistence, the FIDOL factors that define nuisance.

WHY IT HOLDS

Standardized method, screened panel, documented traceability. The result is a number a regulator will accept and an opposing expert cannot wave away.
