Abstract

A sampling device including a preconcentrator and a gas flow device, the preconcentrator including an adsorbent surface over which a sample gas is passed, the adsorbent surface being provided in the region of an orifice of the preconcentrator and the gas flow device being arranged to cause gas to flow through the orifice and radially outward of the orifice.
