Applying the electronic nose in the environment

The communication presents the various requirements imposed to electronic nose to become an instrument of environmental monitoring. Obstacles of the monitoring of real life environmental odours may be classified into three categories:
• the final goal of the study, requiring to measure a global odour annoyance and not any gaseous emission,
• the analysed sample itself, which is highly variable, due to the process evolution and to the influence of ambient parameters;
• and the operating conditions, needing to work far from any building and sometimes at locations not easy to reach.

The paper suggests some simple solutions to those problems.
