CELL FOR X-RAY SPECTROSCOPIC DIAGNOSTICS OF LIQUID-PHASE SAMPLES IN A CONTROLLED ATMOSPHERE UNDER HIGH PRESSURES AND TEMPERATURES IN THE OPERANDO MODE Russian patent published in 2023 - IPC G01N23/83 

FIELD: testing.

SUBSTANCE: area of application: for X-ray spectroscopic diagnostics of liquid-phase samples. Substance of the invention consists in the cell for X-ray spectroscopic diagnostics of liquid-phase samples containing a hollow body with the upper surface thereof equipped with a protrusion wherein a cup with the test sample is installed, made of a polymer non-radiopaque material and equipped with a ledge in the upper part thereof with the outer equal to the outer diameter of the protrusion; a cover rigidly connected to the body and made with holes for the installation of gas supply tubes; a hole is made on the side surface of the body, with a window made of a non-radiopaque material and tightly adjacent to the cup wall installed therein; a securing element with a central hole located, on top of the window and rigidly connected to the side wall of the body; heating elements located in the body channels; and a temperature sensor located in the hole of the body.

EFFECT: possibility of X-ray spectroscopic diagnostics of liquid samples in the operando mode under high temperatures and pressure of the gaseous medium.
