The 10th meeting of the working group 2 dealing with dynamic olfactometry just took place in the beautiful city of Delft, The Netherlands. By this time the work should be mostly done, but it seems that there are still some important issues to deal with. Some interesting topics such as the use of blank fields were once again left aside, but all in all, the number of items reviewed this time was comparatively higher.
The first day and part of the second day were dedicated to the discussion of sampling in olfactometry. Many of the items had been discussed before, but the text needed to be thoroughly reviewed. Mr. De Bree presented a proposal which was reviewed almost line by line. The group worked on many items related to sampling.
Some relevant topics were:
- Representativity of the sample
- Preliminary investigation
- Sample duration
- Cleaning of the equipment
- Sample storage
- Active and passive sources
Ms. Capelly presented a work on Passive area source sampler hoods with an special emphasis on the analysis of gaseous emissions from a solid porous media. She presented a theoretical model for the evaluation of emissions from liquid and solid passive areas which can be used to define a benchmark approach for the sampling system on passive area sources.
Mr. Oxbol presented a calc sheet with an example of the uncertainty calculation with n-butanol and the use of a practical odour. This example will probably go as an Annex in the standard.
The next meeting will take place in October of this year in Bilbao, Spain and will be organized by olores.org. We are looking forward to host this meeting and be a little part of the history of the olfactometry.
