Micrometrics Accelerated surface area and porosimetry system ASAP 2020, MP.C.K.

Model: 
ASAP 2020, MP.C.K.
Supplier: 

The ASAP 2020 is a BET surface area, porosity and chemisorption analyser utilizing gas adsorption. The instrument will be used for the study of microporous and mesoporous materials

including  zeolites, carbons, metal organic compounds, hierarchical pore structures and inorganic structures.

Physisorption:

This is a process by which molecules adsorb onto a surface without the formation of chemical bonds. The weak intermolecular interactions between the surface material of interest and the analysis gas are measured at cryogenic temperatures and the resulting isotherms are used to determine surface area,pore size and pore volume. In some instances pore shape can be inferred from data generated.

 

Chemisorption:

This occurs when the analysis gas absorbs onto the surface of the material via formation of chemical bonds. By performing this analysis over a range of temperatures, the actice sites and relevant thermochemical properties of the material can be determined. The data generated from this technique is extremely useful in determining the physical chemical characteristics such as metal active area on catalysts, acid base sites on inorganic materials, temperature stability and other information.
