Name:
Apparatus for determining the surface area and pore structure of porous materials
Producer:
Micromeritics Instrument Corporation
Model:
ASAP 2020
Research group:
Team 15. Structure and catalytic properties of highly dispersed metals on carrier
Description:

The ASAP 2020 is an automated device for porosimetric measurements and determination of the surface area of porous materials, using the gas sorption technique. An option to determine the microporous structure is available. Additional equipment allows for the conduct of chemisorption measurements, which, using a static volumetric technique, allow for the determination of dispersion, particle size and active surface of metals deposited on the substrate.
