Intelligent physical adsorption instrument

Beijing Haixinrui Technology HL1800 SeriesFully automatic intelligent physical adsorption instrumentFor automated instruments,The principle is based on the adsorption characteristics of gases on solid surfaces. Under a certain pressure, the surface of the tested sample exhibits reversible physical adsorption of gas molecules at ultra-low temperatures. By measuring the equilibrium adsorption amount at a certain pressure, theoretical models are used to determine the physical quantities related to physical adsorption, such as the specific surface area and pore size distribution of the tested sample.
