Odour Monitoring

Protea uses both sensory and chemical techniques depending upon the monitoring objectives.

The most common technique is sensory olifactometry where bag samples are taken and analysed according to CEN EN 13725:2003. Results are expressed in odour units.

If results are required for particular problem components (eg. H₂S, mercaptans, odourous VOCs etc) then chemical techniques such as thermal desorption tubes, GC-MS, and Mass Spectrometry can be used.

Our odour studies are commonly used for:

odour abatement efficiency assessments
odour abatement plant design
Demonstrating compliance to emission limit values (ELVs)
VOC characterisation and odour assessment
Calculation of ground level concentration by Air Dispersion Modelling
