Odour Sampling
TOU has the capability to collect representative samples from almost every type of point, area and volume source of odour. Features of our sampling capability include:
- The use of single use, Nalophan sampling bags
- The conventional 'drum and pump' sampling method to AS/NZS 4323.3:2001
- The ability to sample wet and hot stack emissions, using the in-house developed SupaDiluta to AS/NS 4323.3:2001
- Isolation Flux Chamber and Wind Tunnel Hoods for sampling odorous emissions from solid and liquid area sources
- Routine measurement of emission flow rate, temperature and relative humidity for every sample that is collected.
Odour Testing
TOU laboratories are capable of carrying out the following analyses:
- Odour Concentration method AS/NZS 4323.3:2001 in odour units (ou) by the methods of AS/NZS4323.3:2001
- In-house method for Liquid Odour Potential (ou/mL)
- Odour Intensity and Hedonic Tone based on the methods of VDI 3882
Key features of the use of Dynamic Olfactometry Testing by TOU include:
- 4 to 6 person panels and 3 rounds of testing for each sample
- n-butanol referencing of all testing sessions
- Calibrated and trained professional odour assessors and
- Regular instrumental calibration for dilution accuracy and stability
