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 space but also lowers the system leakage rate.
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.
High-Precision Micropore Distribution Analysis (Micro 100C)
Utilizes advanced micropore models, including the Horvath-Kawazoe (HK) and Saito-Foley (SF) methods, to accurately determine pore size distribution. Ensures an aperture deviation of less than 0.02 nm, providing precise characterisation of microporous materials in gas adsorption studies.
Thermal Stabilisation
A core rod in the sample tube reduces dead volume 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, minimising temperature- related deviations during analysis.
Customisable Selection of Pressure Transducers
Depending on the model, the AMI-Micro 100 Series offers various quantities and types of pressure transducers. Among them, the Micro 100C, equipped with a 1 Torr transducer (selectable 0.1 Torr), enables a partial pressure (P/P₀) of up to 10⁻⁸ (N₂/77 K) in physical adsorption analysis.
Optimised 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 analyser therefore preventing manifold contamination.
Turbo Molecular Pump
A Turbo Molecular pump is included on the Micro 100C. Achieving ultimate pressures of 10⁻⁸ Pa, this system ensures a solid foundation for precis micropore analysis at ultra- low pressures.
Multiple Degassing Stations for Sample Preparation
Equipped with two (2) integrated degassing ports and two (2) in-situ degassing ports. Each port offers independent temperature control from ambient to 400°C (Optional: RT-500°C), ensuring precise sample preparation. In- situ degassing enhances microporous material analysis by providing superior efficiency over ex- situ methods.
PAS Software is an intelligent solution for operation control, data acquisition, calculation, analysis, and report generation on the Windows platform. It communicates with the host via the LAN port and can remotely control multiple instruments simultaneously.
PAS Software adopts a unique intake control method, optimizing pressure in the adsorption and desorption processes through a six-stage setting, which improves testing efficiency.
Each adsorption equilibrium process is dynamically displayed on the test interface. Adsorption characteristics of the sample can be easily understood.
Changes in pressure and temperature inside the manifold can be directly observed in the test interface, providing convenience for sample testing and instrument maintenance. The current state of analyzer can be intuitively understood with the indicator light and event bar.
