Device for measuring the thermodynamic characteristics of adsorption of organic and inorganic substances

摘要

The utility model relates to the field of physical chemistry, specifically to devices and methods for determining the surface properties of substances, and can be used in infrared spectroscopy to determine the thermodynamic parameters of adsorption of a wide range of substances. A device for measuring the thermodynamic characteristics of adsorption of organic and inorganic substances is proposed, which includes a radiation source, a cuvette compartment, a high-temperature cuvette and an infrared radiation receiver, while the high-temperature cuvette in the upper part contains a Peltier element, which makes it possible to regulate and maintain constant the vapor pressure of the adsorbate. The technical result is to accelerate the procedure for establishing equilibrium pressure. 3 fig., 1 tab.
