Abstract: A method of detecting the presence of insects, including larvae, in an indoor environment, which includes the steps of (a) obtaining a sample of volatile organic compounds (VOCs); (b) separating the sampled VOCs; (c) detecting the presence or absence of “target” VOCs from at least one category: “category 1 VOCs”—VOCs emitted independently of the support on which the insects develop and emitted only in an insect infestation VOCs, “category 2 VOCs”—VOCs emitted independently of the support but may have biological origins other than insects, and “category 3 VOCs”—VOCs emitted depending on the support and emitted only in an insect infestation; (d) calculating both an insect infestation index (“3I”) and a limit value (“VL”) based on the presence or absence of the target VOCs; and (e) comparing the “3I” and “VL” values. The environment is infested for a “3I” value strictly greater than the “VL” value.

Abstract: The present invention relates to a particle separator configured to be operatively connected between an enclosure hood and a ventilation system. In practice, an air stream containing particulate matter from an industrial process is directed through an enclosure hood, through the particle separator and into the ventilation system. Relatively large particles are removed from the air stream in the particle separator before the air stream reaches the ventilation system. This reduces the abrasion and general damage that can occur from relatively large particles moving through the duct structure of a ventilation system.
