Comparison between application of questionnaire (VDI 3883) and analytical measurement of TRS (Total Reduced Sulphur Compounds)

le .

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.

Last meeting of the Working Group 2 dealing with the revision of the current standard on dynamic olfactometry

le .

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?

Registration for the EN 13725 Interlaboratory Comparison 2018 is open

le .

ILC2018    The Interlaboratory Comparison for Olfactometry (ILC) based on the Standard EN 13725:2003 has been announced for this year 2018 and once again the company Olfasense is behind the organization. The registration period has started!

   The EN 13725 interlaboratory test gives odour laboratories all around the world the opportunity to demonstrate compliance with their performance requirements and compare the performance of any laboratory internationally. Once year again, the ILC 2018 will be carried out in June, but all interested to participate must register before April 27th.
