4th meeting of the CEN Working Group for 'Instrumental odour monitoring'

le . . Affichages : 17403

wg41 tg2   Olores.org had the privilege of organizing the last meeting of the European Committee for Standardization (CEN) on 'Instrumental odour monitoring’. These meetings were organized last week in our home town of Bilbao, Spain. It was a pleasure to meet all the colleagues in our city and to discuss for two days about odour management and instrumental monitoring.

   In the last meeting of the Working Group (WG) 41 in Delft, after several discussions on the scope of the norm, the title of the norm was changed from 'sensor technologies' to 'technologies for instrumental odour monitoring' instead. One of the reasons behind this decision was a hot debate about including other "odour monitoring" devices such as a Gas Chromatography, for example. However, we will use the word 'o-sensor', to keep it short and to make a clear distinction between these devices and the ones incorrectly named as 'e-noses'.

   The work of this Working Group was quickly done on the very first day. One of the main topics was to take a decision whether to define the design of the o-sensors or to define a framework of requirements for these devices. It was decided that it was more convenient to establish a set of conditions to test any device that will follow this norm. However there is a hard task ahead. These conditions have to be adequate and representative not only in a laboratory, but also for a field deployment of the o-sensors. A mix of several testing gases were proposed but a nice work is ahead for the Task Group (TG) 1 that is defining a minimum requirements for instrumental odour monitoring systems. This group is coordinated by Laura Capelli. The photo shows the members of the TG 1 during the second day of discussions.

   Aspects like cross-sensitivities or false positives have to be taken into account at this stage.

   The Task Group 2 that is establishing and validating the relationship between an odour metric and the real odour, had a very intensive meeting as well that very same day. The following picture shows some of the members of this group.

   It is quite difficult to include in just one article all the items discussed in these meetings of the WG41, nor is the aim of this publication. Most of the European manufacturers of o-sensors are present in this CEN WG, however, there is always a place here for any person interested on this subject. Feel free to contact your national standardization body in case of CEN members to get in touch with this group. Even if you are not European, you can have access to all the documentation published in this group, provided that your country has an organization member of the ISO. Just contact your national representative body.

   As said before, olores.org is very happy to host this meeting and we hope to repeat the experience again any time soon. We would like to say thanks to all the people that attended the meetings for taking the time to come here. We just hope that they had some time to go around our beautiful city of Bilbao.
