Odour Assessment and Control:
Odour assessment can be done by sensory and chemical methods. The sensory approach is used for measuring odour intensity, and the chemical method to determine the nature of the smell. They are both used in control and dispersion methods to eliminate an odour problem. Aspen do many of these assessments.
We collect samples for Olfactometry EN 13725 (The sensory method)
and for GC-MS analysis + interpret the results. EN 13649.
