Abstract
The sampling system of the invention includes a column comprising a first separator associated with a first collector so as to extract particles whose diameter is larger than a first diameter, and a second separator associated with a second collector which eliminates the finest particles and concentrates the other particles in the gas flow sucked up by the suction pipe of an analysis device.
