AMI Micro 300 Series: High-Precision Micropore & BET Surface Area Analyzer
Introduction
The AMI Micro 300 Series is a research-grade gas physisorption system specifically engineered for ultra-low pressure micropore characterization (< 2nm) and high-precision specific surface area analysis. Built for demanding material science research, the instrument features three independently operating analysis stations alongside three dedicated in-situ degassing ports.
Equipped with dedicated dosing manifolds for each port, high-sensitivity 0.1 Torr or 1 Torr pressure transducers, and an optional integrated Turbo Molecular vacuum pump (achieving ultimate pressures down to 10-8 Pa), the Micro 300 Series enables ultra-low relative pressure measurements down to 10-8 P/P0. Supported locally in Malaysia by LMS Scientific Solution Sdn Bhd, the Micro 300 Series is the ideal solution for analyzing challenging microporous materials, including Metal-Organic Frameworks (MOFs), zeolites, activated carbons, and advanced battery materials.

Key Advantages & Design Features
- 3 Independent Analysis Stations: Each analysis port operates completely independently with its own dedicated dosing manifold, allowing simultaneous testing without station-to-station interference.
- 3 In-Situ Degassing Ports: Supports simultaneous sample preparation and analysis. Each degas port features independent temperature control from ambient up to 400°C (optional up to 500°C), eliminating contamination risks associated with ex-situ sample transfer.
- Ultra-High Vacuum Technology: Models 300B and 300C incorporate an integrated Turbo Molecular pump capable of reaching ultimate pressures of 10-8 Pa (7.5 × 10-11 Torr), providing the necessary vacuum level for ultra-fine micropore resolution.
- Precision Sensor Customization: Model 300C offers up to 9 analysis pressure transducers, including high-sensitivity 0.1 Torr or 1 Torr sensors for high-resolution low-pressure data acquisition.
- Low Dead-Volume Integrated Manifold: Built using an integrated metal block manifold design that minimizes internal free space and system leakage rates.
- Real-Time P0 Measurement: Independent P0 pressure transducers monitor saturation vapor pressure continuously in real time for exact P/P0 calculations.
- Thermal Stabilization & Core Rods: Features iso-thermal jackets and sample tube filler rods to minimize cold free space variations and maintain temperature stability along the sample cell.
- Advanced Contamination Control: Segmented multi-channel vacuum control prevents fine powder elutriation into the manifold during evacuation.
Key Applications
The AMI Micro 300 Series is designed for advanced material characterization across Malaysian research universities and industrial centers:
- Metal-Organic Frameworks (MOFs) & COFs: High-resolution micropore profiling, pore volume determination, and low-pressure gas uptake studies.
- Zeolites & Molecular Sieves: Exact aperture sizing and micropore distribution mapping using NLDFT, HK, and SF models.
- Activated Carbons & Biochar: Fine micropore and mesopore structure characterization for gas separation and environmental purification.
- Heterogeneous Catalysts: High-precision BET surface area measurement and pore accessibility testing for microporous/mesoporous catalytic supports.
- Low Surface Area Materials & Powders: Krypton (Kr) gas physisorption capability for precise surface area measurements down to 0.0005 m2/g.
