Abstract
Fluids kept under high pressure in one or several balancing cells (C1, C2) inside a thermostat-controlled enclosure (14) at about 200.degree. C. are extracted by introducing into the enclosure a sampling cell (1) capable of withstanding pressures of the order of 150 MPa, fastening cell (1) to a connection element (24) linked to balancing cells, taking samples and removing the cell from the thermostat-controlled enclosure, with all of these operations being easily conducted from outside. After possible weighing of the sampling cell, a transfer device thereafter allows the sampling cell to be communicated with measuring and analysis devices such as a gasometer associated with a separating bottle, a solvent injection means, etc. Operations are synchronized by a programmed microcomputer (MC). The preferred application is processing geological samples.
