Description
The AMI-Meso 112/222 Series is a precision instrument engineered for accurate surface area and pore size distribution analysis of powdered materials, especially mesoporous and macroporous solids. It comprises two models — Meso 112 and Meso 222 — both integrated with high-accuracy 1000 torr pressure transducers for reliable BET and mesopore characterization. Each analysis station includes an in-situ degassing module (up to 400 °C), enabling direct sample preparation without contaminating transfers.
Key Features
-
In-situ degassing at each station (ambient to 400 °C) to remove adsorbed contaminants and prepare samples for analysis.
-
Independent analysis ports: each station can run independently, enabling simultaneous measurements on different samples.
-
Minimal dead-volume internal gas path via integrated metal module design, reducing measurement error and leak potential.
-
Dedicated P₀ (saturated vapour pressure) transducer at ~133 kPa or alternative atmospheric input, assuring accurate P/P₀ measurement.
-
High-precision pressure transducers (1000 torr) with resolution enabling measurement down to P/P₀ ≈ 10⁻⁴.
-
Comprehensive software support for adsorption/desorption isotherms, surface area (BET, Langmuir, STSA), pore size distribution (BJH, t-Plot, DR, HK, Saito-Foley).
-
Equipped with low-form Dewar flask and sealed cover for temperature stability during the measurements.

Applications
-
Characterization of catalysts, supports, and adsorbents: measure surface area, pore size and volume to predict activity or capacity.
-
Materials research: nanomaterials, powders, metal-organic frameworks (MOFs), zeolites, carbons.
-
Quality control in industries: ceramics, building materials, pigments, activated carbon.
-
Battery and energy materials: electrode materials where surface and porosity influence performance and kinetics.
Why Choose This System?
-
Offers high precision for both surface area and mesopore/macropore analysis within one instrument.
-
Enables simultaneous independent measurements (two ports) boosting throughput.
-
Reduces operator overhead with in-situ degassing and automated measurement routines.
-
Flexible analysis software supporting a wide range of standard models and custom reporting.
Considerations
-
Proper vacuum and cryogen (liquid nitrogen) infrastructure required for accurate BET/physisorption protocols.
-
Sample degassing protocols are crucial for reliable results—operator training matters.
-
While excellent for mesopore/macropore, if your primary focus is ultra-micropores (< 0.7 nm) you may need a dedicated micropore-optimized system.
-
Ensure the chosen model matches your throughput and configuration needs (e.g., dual-port vs higher-port systems).
