Device for collecting and analyzing airborne particles

A collection and analysis device comprising:

• a component incorporating a collection unit for particles and an analysis unit for analyzing the collected particles, the collection unit comprising a collection zone disposed on the component, on which said particles are deposited, collection means configured to force said particles to be deposited against the collection zone, a fluidic elution circuit arranged in said component to elute the particles present in the collection zone, and a control unit configured to control the collection unit and the fluidic elution circuit, wherein:
• said control unit is programmed to control via a control sequence wherein said collection unit and fluidic elution circuit are controlled in a desynchronized manner in order to perform, in a first time, the collection of particles in a dry condition and, in a second time, the elution of the particles in a separate stage from the collection,
• the collection means comprise at least one collection channel produced in the component and comprising an inlet and an outlet to be passed through by a flow of a gas or gas mixture containing the particles, said at least one collection channel being arranged to pass through said collection zone,
• the collection zone is produced in a hydrophilic material,
• the fluidic elution circuit comprises a first fluidic channel emerging on the collection zone,
• the analysis unit comprises a detection chamber incorporated in said component, arranged to collect a liquid drained by the collection zone during the elution,
• wherein the collection zone is produced in an independent membrane produced in said hydrophilic material, deposited on a surface of the component, and
• wherein the component includes a receptacle positioned on an opposite side of the membrane from the first fluidic channel of the fluidic elution circuit.
