This paper will introduce the importance of proper sampling when assessing odours. Generally, when complaints occur in a region, the first step is to investigate any given complaints. Some of the grievances may not be valid due to factors such as wind direction or other meteorological conditions.
How does one determine which complaints are valid? How do you prove that the odour emanating from the “in question facility” is actually from that facility and not a neighbouring facility? How do you determine the “true” odour concentration at the complaint areas?

Scentroid, a very active Canadian manufacturer has presented in the recent NOSE 2014 in Venice their new wind tunnel, the SW60. This very light weight wind tunnel for sampling odours is made of aluminium/composite panels and it has a coating inside of PTFE. In addition, the wind tunnel comes with an internal air supply and tubing with an internal rechargeable battery to do the surface sampling in passive sources easier.
