Overview
The physical adsorption specific surface area analyzer uses nitrogen gas to measure the surface structural characteristics of materials, which can measure the physical adsorption of a wide range of adsorption isotherms, understand the surface area, true density, pore size distribution, porosity, and pore volume of materials.
Product Details
characteristic
- Multiple detection and analysis items: analysis of microporous and mesoporous structures, including surface area, true density, porosity, pore volume, isothermal adsorption desorption curve, average pore size, and pore distribution.
- Analysis method: Physical adsorption and desorption
- Type of adsorbed gas: N2
- Aperture analysis range: required from 1.2nm to 400nm.
- Surface area analysis: 0.01m2/g 以上。
- Large special sample tube design: Adopting a U-shaped sample tube design, it has both capillary and large tube diameter designs, allowing for rapid degassing (Degas) processing in less than 30 minutes.
- Rapid specific surface area detection, completed from degassing to analysis in less than 1 hour.
- The integrated design of the instrument ensures that the sample tubes for Degas and Analysis are placed in the same location, without the need to move the sample tubes, thus guaranteeing the efficiency and effectiveness of sample pretreatment.
- By using a large heating furnace, the sample tube can be wrapped around it, so that the degassing stage (Degas) is not affected by external temperature differences and can perform rapid degassing function.
- Long distance lifting platform and large capacity Dewar flask can be used for long-term analysis and testing.
