Abstract

Fluid sampling device comprising a sampling cell provided with a thermal control valve consisting of a plug made from a solid low-melting temperature alloy that is made permeable to the fluid by heating the metal alloy to its melting temperature. The device mainly comprises an intermediate cell with a central channel provided with a plug made from a low-melting temperature alloy which fits into the inlet hole of the sampling cell. A connecting device for connecting the two cells together and an element which connects the intermediate cell via a fine linking tube to a reactor producing the fluid to be sampled.
