Measurement of specific surface area of porous materials and experimental setup for CO2 capture

SL-SorbMeasurement of specific surface area of porous materials and experimental setup for CO2 capture

The basic principle and method of using this device for ZBET flow adsorption method to determine the specific surface area of solid substances.

This measuring device was jointly developed by Nanjing Sangli Electronic Equipment Factory and Sichuan University

The instrument is designed with an integrated combination of flow control system, adsorption testing system, and constant temperature water bath, making the experimental setup simple and reliable.

Adopting dual gas quality control and display, the system can stably control the flow rate and pressure ratio, which is more suitable for experimental teaching. It has good operability and stable experimental data

The adsorption instrument can automatically shut down, forming a closed system, effectively weakening the exchange of substances with the outside world, reducing data fluctuations, and improving the stability and repeatability of experimental results

The color change of the indicator can be used to determine the endpoint of COz saturation adsorption, increasing the visualization of experimental phenomena.
