Odour Laboratory

(Emissions and Environmental Testing)

The Pinchin odour lab was established in 2000 to meet client needs in environmental odour analysis. Beginning with clients in Southern Ontario, the lab now has a Canadian client base stretching from New Brunswick to British Columbia, as well as clients in the United States and Great Britain.

Pinchin’s odour laboratory and Head Office is conveniently located in Mississauga near Pearson International Airport. The olfactometer and panellist staging rooms are dedicated odour free zones supplied by a filtered air supply and kept under positive pressure to improve ventilation and minimize ambient odour infiltration.

Odour panels conducted at Pinchin follow the olfactometry standards published by the Ontario Ministry of the Environment, the American Society for Testing and Materials (ASTM), and the European Committee for Standardization (CEN). Assessors require regular screening to ensure they are within a defined odour sensitivity range.

To monitor assessor sensitivity, Pinchin follows the European Standard EN 13725:2003 “Air quality – Determination of odour concentration by dynamic olfactometry”, which specifies a sensitivity range much smaller than the normal population to ensure constant results from sample to sample, and from day to day. This is above and beyond the quality control practices required by the Province of Ontario outlined in the Ontario Ministry of the Environment Draft "Source Sampling for Odours," Version #2, February 1989. An AC’SCENT® International triangular forced-choice, ascending concentration, dynamic dilution olfactometer is used with a panel of 8 trained assessors.
