Addressing the Market Demands for Artificial Olfaction Systems

Artificial olfaction system (AOS) instruments, more specifically, electronic noses containing non-specific sensor arrays capable of discriminating and quantifying target environmental odours, e.g. nuisance odours, can provide significant advantages over traditional, human-dependent odour assessment methods. To determine the markets receptiveness, needs and expectations, survey responses from 92 potential AOS users worldwide, including regulators, researchers, and service providers were analysed. There is a general lack of confidence in reliability of odour data using current field methods and dissatisfaction with the costs of conducting lab and field odour assessments. Though not yet commercialised, recognition of AOS-type technology is high and demand for reliable, portable odour sensing devices is strong. Accuracy and reproducibility/precision are considered the two most important factors, followed by sensitivity, portability and cost. A portable field device could expect to retail for $10,000-$15,000 Australian Dollars and should weigh around 10 kg or less. Portability is secondary to reliability, provided the instrument can be left in situ. Including additional sensors to measure specific odorants like H2S is highly desirable, where cost-effective.
