Abstract
It comprises a handle (), an air flow amplifier () leading to a retention means () such as a cyclone via a passage (), and a compressed air inlet device () in the amplifier () that creates a strong suction of outside air, through the nozzle () capable of capturing even fine particles of low content up to a measurable quantity. Being completely devoid of electricity, this device is useful in hazardous atmospheres, in particular for detecting the presence of explosives after analysis of the particles collected by this device. It makes it possible to sample particles in extreme conditions of high or low temperatures.
