Cell for analysing fluid samples under very high pressure and corresponding method of analysis

摘要

The analysis cell has a cylinder (1) in which an axially translatable piston is housed that defines, with walls of the cylinder, a closed compression chamber (10) in which the sample is confined. A side wall (12) of the chamber is provided with a bore (11a,11b) for sealably receiving a measuring element (2) movable inside the chamber between a retracted position retracted into the bore to allow the piston to pass by the measuring element, and a measuring position in which the measuring element protrudes into the closed compression chamber.
