AMI-Meso Series: Meso and Macro-Pores

The AMI-meso can come with one, two, or four sorption analysis stations.  Each station has an independent dosing manifold and a 1000 mmHg transducer.  Each of the stations also includes an in-situ degassing module to allow for treatment of the sample to 400°C. This in-situ degassing prevents any contamination during possible sample transfer. If multiple stations are selected, each station acts independently from one another. The AMI-meso is the most versatile BET analyzer on the market.  

Thus, this BET analyzer/instrument can start experiments on different samples at the same time.  Through software control, the AMI-meso can automatically:

• Dose adsorbate

• Raise and lower the dewar

• Determine if equilibrium conditions are satisfied

• Plot the real-time physisorption isotherm

• Determine adsorption/desorption kinetics 

TECHNIQUES

The AMI-meso, BET analyzer, can display and interpret data in various methods, including:

• Single or Multi-point BET surface area

• Adsorption and Desorption isotherms

• Langmuir surface area

• External Surface Area (statistical thickness method)

• BJH Pore Size Analysis

• t-Plot

• Average pore size, total pore volume
