Abstract: An assembly for checking the atmosphere within a first environment isolated from a second environment, which differs by air quality and/or composition of the atmosphere. The assembly includes an isolation element for isolating the first environment from the second environment, a sampling device to collect elements present in the atmosphere within the first environment, and a suction device. The isolation element has an item of isolating personal protective equipment, and the sampling device includes a cassette defining a compartment having an inlet orifice as the sampling orifice and an outlet orifice as the connection orifice, which can be connected to the suction device, an element for capturing the elements being researched, interposed between the two orifices, in the compartment, the cassette further having an attachment element for mounting the sampling device on the isolating personal protective equipment, and the sampling orifice opening into the isolated first environment.
