The AMI-Micro 100 Series is a high-precision physisorption instrument designed for the accurate determination of specific surface area and pore size distribution in a wide range of materials. The series is available in three distinct models—A, B, and C—each offering specialized capabilities to accommodate various analytical requirements (refer to the specification table for further details).
The Micro 100 C model is equipped with high-sensitivity 1 torr pressure transducers (with an optional 0.1 torr configuration) and a turbo molecular pump achieving an ultimate pressure of 10⁻⁸ Pa, ensuring exceptional accuracy in the characterization of microporous structures. Furthermore, all analysis stations incorporate in-situ sample preparation, effectively minimizing contamination and enhancing measurement reliability.
Engineered for advanced materials research, the AMI-Micro 100 Series is particularly well-suited for the characterization of microporous materials, including metal-organic frameworks (MOFs), molecular sieves, catalysts, activated carbon, and other porous substances, providing precise and reproducible gas adsorption analysis.
Features
Module Design for Minimal Dead Volume
The internal gas path design of the instrument adopts a unique integrated metal module design, which not only reduces the internal dead volume spacebut also helps mitigate possible leaks.
Saturated Vapor Pressure P0
An independent P0 pressure transducer is configured at 133 kPa for P0 value testing,enabling real-time P/P0 measurement for more accurate and reliable test data. Alternatively, an atmospheric pressure input method can be used to determine P0.
Independent analysis ports
With independent analysis ports, the system employs a unique vacuum control logic that allows each station to operate without disruption, even when using a single mechanical pump or pump group. This enables simultaneous, independent experiments, meeting diverse adsorbent testing needs while ensuring high efficiency.
Thermal Stabilization
A core rod in the sample tube reduces deadvolume and stabilizes the cold free space coefficient, while an iso-thermal jacket maintains a constant thermal profile along the tube. Additionally, automatic helium correction ensures precise calibration for any powder or particulate material, minimizing temperature-related deviations during analysis.
High Accuracy Pressure Transducers
Equipped with 1000 torr pressure transducers, the Meso Series enables precise physical adsorption analysis, achieving a partial pressure (P/P0) as low as 10-2 for nitrogen (N2) at 77 K.
Optimized Manifold Contamination Control
This system features a multi-channel, adjustable, and parallel vacuum design with segmented vacuum control. This setup effectively prevents samples from being drawn up into the analyzer therefore preventing manifold contamination.
Liquid Nitrogen Dewar
The use of 1 L Dewar flasks in conjunction with a sealed cover ensures a stable thermal profile along the entire length of both the sample tubes and P0 tubes throughout the testing process.
Sample Preparation
Equipped with four in-situ degassing ports, enabling simultaneous degassing and analysis. Each port offers independent temperature control from ambient to 400°C, ensuring precise sample preparation.
