Advanced Specific Surface Area and Micropore Analyzer
Test Principle
Under low temperature conditions (e.g., liquid nitrogen bath, 77.3K), a certain amount of adsorbate gas (e.g., N₂) is introduced into the sample tube. The adsorption partial pressure is directly measured by controlling the equilibrium pressure in the sample tube, and the adsorption amount at this partial pressure point is obtained through the gas equation of state (PV=nRT). By gradually adding adsorbate gas to increase the adsorption equilibrium pressure, the adsorption isotherm is obtained. By gradually removing adsorbate gas to decrease the adsorption equilibrium pressure, the desorption isotherm is obtained. Compared with the dynamic method, no carrier gas (He) is required, and there is no need to repeatedly raise and lower the liquid nitrogen cup. Since the sample to be tested is in a fixed-volume sample tube, the adsorbate does not flow relative to the dynamic chromatographic method, hence the name static volumetric method.
