ASSEMBLY FOR PICKING AND TRANSPORTING NANOOBJECTS CONTAINED IN AEROSOLS, WITH A CASSETTE THE OPENING OF WHICH IS SECURED DURING THE PICKING

摘要

An assembly for picking and transporting nano-objects, comprises a cassette having first and second components, which are provided with means of mutual assembly and with means for holding the filter. The first and second components define, when the components are in an assembled configuration, a cavity in which the filter is housed and held therein. The means of mutual assembly comprise first clipping means secured to the first component, second clipping means secured to the second component and able to collaborate with the first clipping means so as to clip the two components together. A picking device comprises suction means to which the cassette is able to be removably attached. The first and second clipping means are configured such that they are not accessible from the outside when the components are in the assembled configuration with the cassette fixed to the device.

主权项

1. An assembly for sampling and transporting of nano-objects present in an aerosol for analysis, comprising:
a device comprising a porous sampling filter configured to trap nano-objects in suspension in the aerosol, a cassette composed of a first piece and a second piece provided with means of mutual assembly and means of holding the filter, the first and second pieces, in an assembled configuration, defining a cavity in which the filter is held, and at least one gasket configured to produce tightness between the cavity and an environment external to the cavity, the means of mutual assembly comprising first clipping means integrated with the first piece, second clipping means integrated with the second piece and being configured to cooperate with the first clipping means in order to bring about a clipping of the two pieces; a sampling apparatus comprising means of aspiration and a seat in which the cassette can be secured in a removable manner when the two pieces are in the assembled configuration to accomplish the sampling of contaminants by means of aspiration, in which assembly an arrangement of edges of the seat for fixation of the cassette relative to the first and second clipping means is such that the first and second clipping means cannot be reached physically, either manually or by a tool, when in the assembled configuration of the pieces, and when the cassette is secured to the apparatus.
