| 시설장비 설명 | Up to 3 samples can be measured independently and simultaneously. Pore sizes of 0.35 to 200 nm in diameter can be measured. Specific surface areas as low as 0.01 m2/g can be measured. Up to 4 BELSORP-miniII units can be controlled from one computer. Liquid nitrogen level control is no longer necessary by applying advanced free space measurement method (AFSM) invented by BEL which obtains high precision and high reproducible data. Very compact space-saving unit ISO 9277 and JIS Z 8830 compliant BEL Japan has developed a unique method to compensate for dead volume in the sample tube. Conventional instruments require that the level of liquid nitrogen is kept constant during a sample measurement. This creates problems with temperature variations in the top of the tube large consumption of liquid nitrogen or requires a complicated liquid nitrogen system. The BELSORP-mini does not require a constant liquid nitrogen level. The change in dead volume due to changes in liquid nitrogen level and temperature and atmospheric temperature are measured in another sample tube. For high precision measurements this is performed at the same time as a measurement but for high throughput applications this can be measured prior to the sample measurement. This method compensates for dead volume changes throughout the whole apparatus and so allows high accuracy data to be collected without time consuming or wasteful liquid nitrogen management. The analysis software for BELSORP-mini is Windows based. Analysis data can be saved in CSV format to be opened in other spreadsheet software packages. The software is very user friendly making it possible to produce good quality analysis printouts for reports or notebooksMeasurement principle: Volumetric gas adsorption method +AFSM Adsorptive: N2 Ar CO2 H2 and other non-corrosive gases Analysis port: High accuracy mode ? 3 ports Standard mode ? 2 ports Specific surface area: 0.01m2/g and above (N2/77K depends on sample density) Pore size distribution: 0.35 ? 200 nm in pore diameter Pressure transducer: 133 kPa (1000Torr) ? 0.5 % of F.S.
