10 years in the making

"Great spirits have always encountered opposition from mediocre minds. The mediocre mind is incapable of understanding the man who refuses to bow blindly to conventional prejudices and chooses instead to express his opinions courageously and honestly."

--- Albert Einstein

The latest olfactometer not only measures the odour concentration at the source where the odour is released, but also evaluates the odour sensation at the location where the odour is perceived. The dilution-to-threshold technique has limited its application to some strength odour samples. The direct evaluation of the odour attributes in the laboratory is suitable for ambient odour monitoring. This new approach extends the current technology and completes the missing link in odour measurement. It also provides better detection limit for investigating odours in the field than chemical analysis. 

At the turn of the millennium, odour concentration measurement standards have been published in many countries after more than half a century of research. It is no doubt that the standardisation has reduced the large variation in odour analysis results. But, the overall performance from the odour testing laboratory in the past 10 years is a long way from industry expectations. Anecdotal evidence suggested that most olfactometer systems have yet to demonstrate compliance with the published standards.
