Cell for analyzing a fluid which is condensable, at least in part
First Claim
1. In a cell for analyzing a fluid which is condensable, at least in part, said cell forming a volume in which the fluid is inserted, said volume being delimited firstly by an outer envelope and secondly by an upper piston slidably mounted in a sealed manner in said outer envelope and means for slidably shifting said upper piston for adjusting the pressure of the fluid being analyzed, lower means within said outer envelope for adjusting the level of the gas/liquid separation surface, said outer envelope including portholes for displaying and measuring the level of said surface, means provided between the piston and said lower means for inserting the fluid to be analyzed into said volume and for emptying said volume of said fluid, the improvement wherein said means for slidably shifting said upper piston comprises a rod of a first control actuator linked to said upper piston, and said lower means for adjusting the level of said gas/liquid separation surface includes a lower piston slidably mounted within said outer envelope connected to a rod of a second control actuator.

Abstract
A cell (4) for analyzing a fluid which is condensable, at least in part. The cell comprises a volume (16, 17, 18) in which the fluid is inserted. The volume is delimited firstly by an envelope (11, 12, 13) and secondly by an upper piston (14) capable of sliding in a sealed manner in the envelope and associated with apparatus for adjusting the pressure of the fluid being analyzed, together with lower apparatus enabling the level of the gas/liquid separation surface to be adjusted. The envelope is provided with portholes (19) associated with marking in order to display and measure the level of the surface. Conduits (20, 21) are provided between the piston and said lower apparatus for inserting the fluid to be analyzed into the volume and for emptying the volume of the fluid. The cell includes the improvement whereby a rod (27) from a first hydraulic control actuator is linked to the upper piston and a lower piston (15) is connected to a rod (29) from a second hydraulic control actuator.
