Product Description:
Thin Layer Chromatography Silica Gel is a white, high-purity powdered silica gel used as a strong polar solid adsorbent for thin-layer chromatography (TLC). It is a porous material with a specific pore size distribution and surface hydroxyl groups.
Different components in a mixture have different adsorption and desorption rates on the silica gel surface, allowing effective separation and purification. Its narrow particle size distribution provides fast separation, high sensitivity and good resolution.
The product 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:
Thin Layer Chromatography Silica Gel is mainly used for coating thin-layer chromatography plates and for qualitative and quantitative analysis of various organic compounds.
It is widely used in:
Pharmaceutical industry
Plant chemistry
Food chemistry
Biotechnology
Clinical chemistry
Chemical and materials research
Environmental chemistry
Life sciences
Teaching and laboratory research
Thin Layer Chromatography Silica Gel can also be used as a carrier for dry cleaning agents.
Packaging:
Customized packaging is available upon request.
Storage:
Store in a dry place. Keep the outer packaging away from direct contact with the ground and avoid damage during handling.During transportation, protect the product from rain, moisture and direct sunlight to maintain product performance.
