leo olfactometer   In the 6th International Conference on Environmental Control Odor Monitoring - NOSE2018 in Milan (Italy) 9-12 September 2018, ARCO Solutions srl, spin off company of the Department of Chemistry and Pharmacy of University of Trieste, presented for the first time its new product LEO - Light Evolution Olfactometer.

   An Olfactometer with 4 panel port designed according to the EN 13725: 2003 and fully automated with 29 dilution steps. Leo is a Dynamic Olfactometer developed for use in laboratories and on-site activities (mobile labs). During the conference the work “Testing Performances of a Newly Design Olfactometer" was also presented, in which the first results of a comparison were made on some samples between the new product and the market benchmark.

zacarias   The aim of this study was to validate olfactometric measurements made in neighborhood of facilities that emit odours at the same time measure the impact on the nearby population before and after installation, and operation of equipment to mitigate odors.

   Olfactometric techniques used in this work are to implement a questionnaire to citizens that could be affected by odours, and then take the values obtained to know odour intensity. On the other hand, they were measured for air quality by chemical analysis. The scope of this investigation was olfactometric measurements for a period of 18 months, as well as chemical analysis. Olfactometric measurement procedures were made using the German regulation VDI 3883 Part 1 and 2.

en13725 meeting trieste   It is over. This meeting that took place in February in Trieste, was the last one on the series of the Working Group (WG) 2. The first meeting took place in Barcelona in November 2012 and after five and a half years of discussions, the first draft is here.

   Some of the hot issues, that have arisen during the last meetings were brought again to the experts. Will there be finally more assessors doing the olfactometric measurement? Will the time to analyse a bag after sampling change? Will there be a new reference substance to calibrate the panel? Will there be a new design of sampler for passive sources? How will be finally uncertainty handled?
