Abstract: A sensor for the continuous in-situ analysis of an aerosol flow for measuring the mass of the micron/submicron particles suspended in the air flow, including an aeraulic sorter allowing the particles to be sorted according to their size with an impactor body with a cascade of one or more stages; at least one MEMS microbalance per stage, with an oscillating silicon membrane located on the impaction zone of the particles; processor connected to each MEMS microbalance to determine the mass of all the particles on the impaction zone; a system for cleaning the MEMS microbalances allowing the evacuation of the particles from the MEMS microbalances; means for driving the aerosol flow.

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 method for viral decontamination of a confined space, in particular of the air present in a confined space, based on application of a relative humidity of at least 50% created in said confined space, or incorporated at the level of a centralized air treatment system or an autonomous air purifier.

Abstract: The invention relates to a method for detecting Serpula lacrymans contamination in an internal environment, taking into account the absence and presence of VOCs produced by the metabolism of Serpula lacrymans, especially by means of the calculation of a contamination index.

Abstract: The present invention relates to a device for detecting a fungal contamination in an internal environment, to the use thereof and also to a method for detecting a fungal contamination in an internal environment using such a device.

Abstract: This invention relates to a device for detecting fungal contamination in an interior environment, including: a concentration module (MC); a separation module (MS) including a chromatographic microcolumn; and a detection module (MD), characterized in that it includes at least one first solenoid valve (E3) upstream of the detection module (MD) enabling either to direct a flow containing target molecules toward the detection module (MD), or to direct a flow filtered by a first means for filtering (Tx1), enabling the detection module (MD) to be cleaned when the flow does not contain the target molecules. The invention also relates to a control interface of the device.

Abstract: The present invention relates to a process for determining mycotoxin production in an interior environment which includes a search for a chemical fingerprint comprising at least one target molecule that is a VOC, optionally cyclic, associated with mycotoxin production, preferably selected from the group comprising cububene, cadiene, copaene, ylangene, D germacrene, muurolane, 1,1-dimethylbutylbenzene, 1,1,2-trimethyl-propyl-benzene, 1-hexyltetradecylbenzene, tetratetracontane, 1-ethyldecylbenzene, hydroxytoluene butylate, 1-butyloctylbenzene, 1-propylnonylbenzene, 2-methylisoborneol and at least one sesquiterpene.

Abstract: This invention proposes a method comprising the steps of: (a) taking an air sample in an indoor environment, then (b) detecting Microbial Volatile Organic Compounds (MVOCs) in the sample. The step (b) comprises searching for a chemical imprint comprising at least one target molecule that is an MVOC associated with an aspergillus metabolism. Thanks to the invention, detection of such target molecules is easier and faster than detection of aspergillus strains or soluble aspergillus metabolites.
