AELAB Chromatography Media is developed using advanced technology with silica gel as a matrix, further modified through grafting, capping, and end-capping processes. Designed for pharmaceutical, biochemical, and chemical separations, it ensures high reproducibility, stability, and efficiency across laboratory and industrial applications.

Main Product Types

1. Amorphous Packing

Made from high-purity, low-metal silica with a very high surface area

Functional groups such as C18, C8, C4, phenyl, amino, diol, sulfonic acid, etc. can be bonded

Ideal for SPE, Flash chromatography, and large-scale industrial separation

Specifications: particle size 40–60 μm, pore size 60–100 Å, surface area 300–550 m²/g

2. Spherical Packing

Uniform particle sizes (5–60 μm) and pore sizes (60–300 Å)

High pressure resistance and reproducibility

Suitable for HPLC and Flash column applications

🔬 How It Works?

Chromatography Media works by providing a highly porous silica gel matrix with functional group modifications tailored for separation. The silica surface is bonded with groups like C18, NH₂, or HILIC, enabling specific interactions between compounds and the stationary phase. When solvents flow through the column, components are separated based on polarity, charge, or hydrophobicity — ensuring high efficiency and reproducibility for both small-scale analysis and industrial-scale purification.
