Activated Alumina Microspheres | High-Precision Catalyst Support & Adsorbent Media | Catalyst Carrier & Industrial Adsorbent

1. Product Introduction & Core Advantages

Aogochem's Activated Alumina Microspheres are engineered, micron-scale spherical particles of high-purity gamma alumina (γ-Al₂O₃), produced through advanced processes to achieve exceptional uniformity. Characterized by their high specific surface area (250-350 m²/g), controlled pore structure, and perfect spherical geometry, they offer a superior combination of high catalytic activity, excellent mass transfer properties, and low flow resistance. This makes them an ideal precision material for applications where performance and consistency are paramount.

These microspheres serve as premier supports in high-performance liquid chromatography (HPLC) and catalyst carriers for laboratory research, pilot plants, and specialized small-scale industrial processes. Their high surface area and tunable surface chemistry also make them effective as high-capacity adsorbent media for the purification of fine chemicals and pharmaceuticals. For R&D centers and high-tech industries in the MENA and CIS regions, they enable breakthroughs in separation science, catalytic screening, and high-purity production.

We supply Activated Alumina Microspheres with customizable particle size, pore diameter, and surface acidity/basicity. Their monodisperse nature ensures reproducible packing and reliable performance. Partnering with Aogochem provides access to this high-precision material, along with technical consultation to select the optimal grade for your specific analytical or catalytic challenge, supporting innovation and efficiency in your advanced processes.

2. Technical Specifications & Performance Data

The value of these microspheres lies in their precise physical and chemical properties, tailored for demanding applications.

3. Primary Application Industries

Activated Alumina Microspheres are critical in fields requiring precision, reproducibility, and high performance.

• Chromatography & Separation Science: The premier application. Used as the stationary phase packing material in Normal-Phase HPLC columns for the high-resolution separation of polar compounds, isomers, pharmaceuticals, and natural products. Their spherical shape and uniformity are key to achieving high column efficiency and peak symmetry.

• Catalysis Research & Fine Chemical Synthesis: Serve as ideal catalyst carriers in micro-reactors, fixed-bed reactors for high-throughput screening, and the production of high-value fine chemicals and pharmaceutical intermediates. Their high surface area allows for excellent dispersion of active metal sites.

• Specialized Adsorption & Purification: Used as adsorbent media in guard columns to protect analytical columns, in solid-phase extraction (SPE) cartridges, and for the small-scale purification of sensitive process streams or solvents.

5. Handling & Operational Guidelines

• Column Packing (Chromatography): Packing HPLC columns requires specialized equipment and expertise. Use recommended slurry packing techniques with appropriate solvents and high pressures to form a stable, high-efficiency bed. Aogochem can provide general guidance for qualified practitioners.

• Reactor Loading (Catalysis): For fixed-bed micro-reactors, ensure gentle and consistent loading to create a uniformly packed bed with minimal voids or channeling, maximizing catalyst effectiveness.

• Conditioning: Prior to first use, columns or adsorbent beds should be conditioned with the relevant mobile phase or solvent to equilibrate the surface and remove any fines.

• Cleaning & Regeneration: Depending on the application, microspheres can often be cleaned by solvent washing or thermally regenerated. Consult our technical team for specific protocols based on the nature of the contamination.

• Storage & Safety: Store in a clean, dry, and sealed container. Although chemically stable, handle as a fine powder using appropriate laboratory hygiene practices (gloves, eye protection). Refer to the Safety Data Sheet (SDS).
