The presence of odour can cause complaints in residential areas or at the indoor area of buildings (offices, homes, hospitals, industries). In many cases odour derives from a number of compounds which have a particularly low odour threshold. That means that those compounds smell or have an annoying odour at very low concentrations (ppb) such as aldehydes and ketones, etc.
Odour concentration is measured in οu/m3 units. N-butanol is used as a standard gas in order to calibrate the laboratory team members to perform the measurements. The odour concentration is measured using EN13725 standard dynamic olfactometer method. An alternative method of odour field measurement is the GRID method (EN16841-1).
We perform odour concentration measurements by using calibrated equipment.
