Information
Thin-layer chromatography silica gel plate is made of high-purity thin-layer chromatography silica gel (powder) mixed with a certain amount of binder and sprayed. The surface of the plate is pure white, flat, uniform and fine.
The main component is SiO2·nH2O, which has stable chemical properties and does not react with other acids and bases except strong bases. Thin-layer chromatography silica gel plates can be directly used for qualitative or quantitative analysis of various types of organic substances.
Anchor use
It has been widely used in the identification of trace impurities and main components of medicines, pesticides, herbal medicines, organic chemical products and grains and foods. At present, it is used in new materials, POM plates and POM rods, and it has also played a role in judging inferior oil.
TLC Silica Plate Classification
The specifications of the silicone plate are divided into: G, H, GF254, HF254.
So what exactly do these models stand for? What are they based on?
"Silicone H" - no adhesive;
"Silica gel G" - containing calcined gypsum binder;
"Silica gel HF254"--contains fluorescent substances, which can be used to observe fluorescence under ultraviolet light with a wavelength of 254nm;
"Silica gel GF254" - contains both calcined gypsum and fluorescent agent.
Another very simple way to distinguish and classify is that different types of silica gel have different gypsum content, which is reflected in the different viscosity of silica gel. The higher the gypsum content, the more viscous it is. This is marked on the bottle that sells silica gel. For example, silica gel H is very loose, and silica gel G generally has a moderate viscosity.
Anchor Features
Thin-layer chromatography silica gel plate is characterized by high sensitivity, clear spots, non-diffusion, good separation effect and short time. It is precisely because of these characteristics that it can be widely used in the market.
