Abstract
Fluid sampling device comprising a sampling cell (1) provided with a thermal control valve having a plug (21) made from a solid low-melting temperature material that is made permeable to the fluid by temporary heating. The device comprises an intermediate cell (6) with a central channel (7) provided with a plug made from the solid material, which communicates an inlet with a first end and an outlet with the opposite end, and suited to tightly fit into the inlet hole of the sampling cell, a device (12, 13) for connecting the two cells (1, 6) to each other and an element (14) associated with a seal (20) for connecting, at the inlet of intermediate cell (6), a linking tube (15) to a reactor (17) producing the fluid to be sampled.
