Disclosed is an analysis cell for the analysis, at very high pressure and high temperature, of fluid samples comprising a cylinder () in which an axially translatable piston is housed that defines, with the end walls of the cylinder, a closed compression chamber () in which the sample is confined, characterized in that the walls of said chamber () are provided with at least one bore () designed for sealably receiving an optical measuring element () 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.

Cell for very high pressure analysis of fluid samples and associated measuring method

Device for measuring thermodynamic characteristics of a fluid sample, comprising in combination: a high-pressure cell () equipped with a motorized piston, a drying oven surrounding the cell and intended to vary the cell temperature, motorization means arranged outside the drying oven, means for stirring the fluid placed within the cell, a frame supporting said oven and means () for tilting said frame so as to tip the cell up. The cell comprises:&#x2014;a specific head for measurements on condensate gas wherein a chamber () of elongate shape along the axis of the cell is intended to collect the liquids, and&#x2014;means () for visualizing the position of the liquid/gas interface.
