Thin-layer chromatography silica gel

Thin-layer chromatography silica gel as the white powder, ordinary (SG12-1) and efficient (SG12-2).
Main component of SiO2. NH2O, insoluble in water, inorganic acid and other organic solvents, soluble in HF and strong caustic solution, can absorption of moisture in the air.
For adsorption of different substances on the difference of retention time, can make all kinds of material to achieve separation and purification.
H, HF254 type, type G, GF254 type.
H excluding gypsum and organic binder;
HF254 containing inorganic phosphor, appear in uv wavelength of 254 nm yellow-green fluorescence;
G type contains 13 5 � � � right gypsum as adhesive, slightly acidic.
GF254 type contains half water gypsum and inorganic phosphor, show yellow-green fluorescence in the ultraviolet wavelength 254 nm.
This product can be directly used for a variety of types of organic material fast separation, qualitative and quantitative analysis, in medicine, pesticides, Chinese herbs, organic chemical products and food, food trace impurities and has been widely used in the main ingredients of identification.
The efficient thin-layer chromatography silica gel particles is more uniform, the characteristics of the fine, compared with the ordinary thin-layer chromatography silica gel, its for material separation effect is better.
