The committee CL019 of Environment in the Chilean National Standardization Institute (INN) has begun a process to approve a new norm for sampling odours for dynamic olfactometry based on the existing German Norm VDI 3880. The new prNCh3386 Norma Muestreo estático para olfatometría (Standard Static Sampling for Olfactometry) will introduce several new requirements for a better representativeness of a sample. This way Chile will have a more advanced standard on odour sampling.
Although many aspects of odour sampling will be included in the revised European standard EN 13725, the Chilean Normalization body has understood that there are still a few years left to see the new norm as a reference. In fact, there is a very detailed procedure for sampling odours in the already published as the German Norm Norm VDI 3880, Static sampling. olfactometry. Therefore there is a group of people led by the INN discussing about including several aspects of this standard on a new Chilean standard: the new NCh3386 Norma Muestreo estático para olfatometría.
This is the first sampling drone to our knowledge that it is able to sample plumes such as those from flaring at elevation of up to 120 meters above ground level that were previously very difficult to accomplish. Scentroid has released this new device that will make sampling at very complicates heights easier. 
The use of general purpose steady state Gaussian models (e.g. AERMOD) for predicting Odour exposure levels around the vicinity of an industrial site has been considered an accepted practice for many countries around the world for more than a decade now.
