Thin layer chromatography silica gel plate

Thin layer chromatography silica gel plate

The efficient thin layer chromatography silica gel plate produced by our company is made of high quality thin layer chromatography silica gel mixed with appropriate adhesive. The product has specified pore volume, surface area, and pore size distribution, which can be directly applied to fast separation of multiple organic substances—qualitative or quantitative analysis, which has been widely used in evaluation on trace impurities and major components of medicine, pesticide, herbal medicine, organic chemical products, grain, and food, especially, it is suitable for separation and detection of some trace and substances difficult to separate owing to complex compositions.

The advantage of efficient thin layer chromatography silica gel plate is good separating effect, high tower levels, and small dispensing spots, which is convenient for serial analysis, with short separating time, high sensitivity, clear spots, and indiffusion. The main component of thin layer chromatography silica gel plate produced by our company is SiO2.nH2O, without causing acid-base reaction other than alkali and hydrofluoric acid.
