Delayed Olfactometry

Overview

A time-lag between sampling and measuring of odour concentration where the odour sample is preserved in an appropriate container (odour-neutral material). It can also be referred to as static sampling. Delayed olfactometry is the analytical technique used in the UK. EN13725 stipulates a maximum temperature during storage of 25°C and samples must be analyzed within 30 hours from the moment of collection. This temperature can be exceeded when working in hot environments provided the deviation is justified in the final report.
