In December 2006, Olores.org visited the facilities of St Croix Sensory in Lake Elmo, Minnesota, USA.  St. Croix Sensory is a sensory testing and training company that specializes in odor testing of air samples, commercial products, and materials and in training of odor assessors, monitors, inspectors, and investigators. Likewise, St. Croix Sensory manufactures state-of-the-art odor sampling and odor measurement equipment. Their products set the standard in odor sampling, testing, and measurement.

  In December 2006 we paid a visit to this firm to know a little bit more about their activities. During this visit, we could have a look to the process of manufacturing the olfactometer AC´Scent. The AC´Scent olfactometer has incorporated its own fresh air pump device with a special filter to assure you get an odorless air for testing, this is a special feature that makes the difference with other olfactometers in the market which usually come with no pump incorporated. Other devices might be smaller but at the end you need to acquire also an air pump and active carbon filters.

Some issues with odours with a company dedicated to transform agricultural byproducts.

  This study started the 13th of October of 2005 and it is set down to end in April 2007. It is one of the first experiences with e-noses in Spain and it is being carried out by the company J. Canet in collaboration with Jaume I University of Castellon and the Regional Ministry of Catalonia.

Following many complaints from neighbours on the surroundings, the company J. Canet started a program in its factory in ALMASSORALA, to determine if their factory is the responsible for the odours. The company claims that there are other activities that could have some influence on the odours in the area.

E-noses are distributed in different areas around the activity and the network is completed with a weather station. The aim is to have a continuous map of odour pollution.
