Abstract
Disclosed is an analysis cell for the analysis, at very high pressure and high temperature, of fluid samples comprising a cylinder (1) in which an axially translatable piston is housed that defines, with the end walls of the cylinder, a closed compression chamber (10) in which the sample is confined, characterized in that the walls of said chamber (10) are provided with at least one bore (11) designed for sealably receiving an optical measuring element (2) movable inside said chamber between a retracted position retracted in the bore to allow the piston to pass, and a measuring position in which it protrudes in said chamber. The invention also relates to a method for detecting and/or measuring the quantity of solid matter using said cell.
