AMI Meso Series

Meso & Macropores

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 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


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
