What is claimed is: 1. A device for collecting and separating particles and microorganisms present in ambient air, the device comprising means for sucking air into a centrifugal enclosure having means for retaining particles or microorganisms and means for exhausting of the sucked-in air, wherein the enclosure is removably mounted on the device and forms a receptacle for transporting collected particles and microorganisms, and wherein the enclosure comprises a small volume cylindrical chamber having volume less than about 200 cm3, in which the particles and microorganisms conveyed by the sucked-in air are set into rotation about the axis of the enclosure and are separated from the sucked-in air by centrifuging against the inside wall of the enclosure, said enclosure co-operating with the air suction means to constitute a self-contained, portable assembly that can be manipulated using only one hand. 2. A device according to claim 1, wherein the means for sucking air into the enclosure is adapted to produce a flow rate of air sucked into said enclosure in the range about 200 L/min to 400 L/min. 3. A device for collecting and separating particles and microorganisms present in ambient air, the device comprising means for sucking air into a centrifugal enclosure having means for retaining particles or microorganisms and means for exhausting of the sucked-in air, wherein the enclosure is removably mounted on the device and forms a receptacle for transporting collected particles and microorganisms, wherein the enclosure includes automatic closure means for closing its top end, which means are open while the enclosure is mounted on the device and are closed while the enclosure is separate from the device. 4. A device according to claim 3, wherein the automatic closure means comprise an annular diaphragm, and resilient means for urging the diaphragm towards its shut position. 5. A device for collecting and separating particles and microorganisms present in ambient air, the device comprising means for sucking air into a centrifugal enclosure having means for retaining particles or microorganisms and means for exhausting of the sucked-in air, wherein the enclosure is removably mounted on the device and forms a receptacle for transporting collected particles and microorganisms, wherein the enclosure is mounted on the device by resilient snap-fastening or by turning through one-fourth of a turn. 6. A device for collecting and separating particles and microorganisms present in ambient air, the device comprising means for sucking air into a centrifugal enclosure having means for retaining particles or microorganisms and means for exhausting of the sucked-in air, wherein the enclosure is removably mounted on the device and forms a receptacle for transporting collected particles and microorganisms, wherein the enclosure is mounted on a main top wall including an axial air outlet and a tangential air inlet. 7. A device according to claim 6, including means for injecting liquid into the top portion of said enclosure, and wherein the liquid injection means comprise a plurality of orifices opening out into said enclosure, that are regularly distributed around a circumference of a rim of the main top wall. 8. A device according to claim 6, wherein said axial outlet of the enclosure is designed to be connected to an air suction socket. 9. A device according to claim 6, wherein the air suction means are secured to the main top wall and suck in air through the axial outlet of the enclosure. 10. A device for collecting and separating particles and microorganisms present in ambient air, the device comprising means for sucking air into a centrifugal enclosure having means for retaining particles or microorganisms and means for exhausting of the sucked-in air, wherein the enclosure is removably mounted on the device and forms a receptacle for transporting collected particles and microorganisms, including means for injecting liquid into the top portion of said enclosure. 11. A device according to claim 10 wherein the means for injecting liquid open out into a duct for admitting air into said enclosure. 12. A device for collecting and separating particles and microorganisms present in ambient air, the device comprising means for sucking air into a centrifugal enclosure having means for retaining particles or microorganisms and means for exhausting of the sucked-in air, wherein the enclosure is removably mounted on the device and forms a receptacle for transporting collected particles and microorganisms, including a handle containing a tank of liquid, means for putting the liquid in the tank under pressure, and means for connecting the tank to means for injecting the liquid into the above-mentioned enclosure. 13. A device according to claim 12, wherein said connection means include means for adjusting the flow rate of liquid towards the injection means. 14. A device according to claim 12, wherein the handle includes control means for controlling the air suction means. 15. A device for collecting and separating particles and microorganisms present in ambient air, the device comprising means for sucking air into a centrifugal enclosure having means for retaining particles or microorganisms and means for exhausting of the sucked-in air, wherein the enclosure is removably mounted on the device and forms a receptacle for transporting collected particles and microorganisms, wherein the removable enclosure is for single use, or is made of a material suitable for putting in an autoclave. 16. A device for collecting and separating particles and microorganisms present in ambient air, the device comprising means for sucking air into a centrifugal enclosure having means for retaining particles or microorganisms and means for exhausting of the sucked-in air, wherein the enclosure is removably mounted on the device and forms a receptacle for transporting collected particles and microorganisms, wherein the means for exhausting air from said enclosure include a filter for capturing particles and microorganisms of dimensions smaller than about 1 μm. 17. A self-contained and portable kit for separating and collecting particles and microorganisms present in ambient air, the kit comprising a device for collecting and separating particles and microorganisms present in ambient air, the device comprising means for sucking air into a centrifugal enclosure having means for retaining particles or microorganisms and means for exhausting of the sucked-in air, wherein the enclosure is removably mounted on the device and forms a receptacle for transporting collected particles and microorganisms, together with a bag of accessories comprising removable spare enclosures; at least one tank of injection liquid; and at least one rechargeable battery.
