Product Description:
Column Chromatography Silica Gel is a high-purity porous silica adsorbent used for the separation and purification of chemical compounds by column chromatography. Its surface contains active silanol groups (Si–OH), which interact with different components in a mixture and enable separation based on their different adsorption and retention characteristics.
The product is specially manufactured with controlled pore size distribution and surface hydroxyl groups. It features high purity, low impurity content and uniform particle size distribution, contributing to stable column flow, high column efficiency and good separation resolution.
Column Chromatography Silica Gel is non-toxic, odorless and insoluble in water and organic solvents. It is chemically stable except when reacting with hydrofluoric acid and hot strong alkalis.
Applications:
Column Chromatography Silica Gel is widely used for separation and purification in:Pharmaceutical sciences
Plant sciences
Biotechnology
Fine chemicals
Organic synthesis
Material science
Life sciences
Environmental science
Grain and food industries
Grades:
