Micropore Analyzer

Micromeritics ASAP 2020 Automatic Micropore and Chemisorption Physisorption Analyzer is a high-performance physical adsorption analyzer which can be applied for producing research grade analytical measurements to determine active metal surface area and dispersion by chemical adsorption and surface area and pore size distribution by physical adsorption under a high vacuum condition.

Specifications:

• One analysis station

• Micropore volume: detectable within 0.0001cc/g

Applications:

• BET (Brunauer-Emmett-Teller) surface area
• Langmuir surface area
• Pore volume and pore area distributions
• Active metal area
• Strong and weak chemisorption
• Percent active metal

Notes to users:

First-time users must be trained by equipment-in-charge before they can use the instrument independently.
