The main component of chromatography silica gel is silica. Due to its different adsorption retention times for different substance components, it can achieve the separation and purification of different mixed components.
There are three types of specifications: Type A（30Å）, Type B（60Å）, Type C（90Å）and Macroporous silica gel(pore size: 120/150/200Å). Other specific parameters can be customized according to needs.

Solid phase extraction is a sample pretreatment developed from chromatography for extraction, separation, and concentration. It is mainly used for sample pretreatment of target compounds in various food, agricultural and livestock products, environmental samples, and biological samples. Solid phase extraction technology has been widely used in many national standards (GB/T) and industry analysis standards.
