摘要

The idea and programs for an automatic microcomputer driven multiple-sample apparatus for measurements of gas adsorption is presented. The Surfamat-5x system is useful for determination of specific surface area and porosity of solids by analysis of adsorption isotherms of nitrogen at the temperature of a liquid nitrogen bath. The system consists of a five-channel measuring unit and a CP/M microcomputer-based control unit with FORTRAN/ASSEMBLER programs for control and interpretation of measurements. The measurement control/optimization and data interpretation programs were intensively developed and the MS-DOS interpretation program was prepared. Raw data stored in disk files by control programs are transferred to an MS-DOS computer for further interpretation. The interpretation program allows us to choose among many models of adsorption/desorption and condensation/evaporation in mesopores as well as adsorption in micropores depending on the kind of solid investigated.
