- Column chromatography is also called preparative liquid chromatography. It is the main chromatographic technique used to separate and refine the industrial material.
- The column chromatography mainly used to separate and refine traditional Chinese herbal medicine, synthetic chemicals and bio-active substances to get high-purity substances by absorption.
- It is also used to absorb high molecular protein during industrial fermentation, to refine organic substance by method of dehydration, to remove the foreigners in edible vegetable oil and petroleum product by absorption.
- Recent years, the application of column chromatography increases fast in the bio-pharmaceutical field. It is already used in the industrialized production of artemisinin drugs, paclitaxel, solanesol, polyphenols and catechin, coenzyme Q10, urokinase acid etc…
- Thin Layer Chromatography Silica Gel and Silica Gel Plate
- Thin layer chromatography silica gel is used in the rapidly qualitative or quantitative analysis of organic substance.
- It is widely applied to identify and to separate the main ingredients of the medicine, pesticides, Chinese herbal medicine, food and chemical products.
- To clean the impurities from them.
- There are four types common used thin layer chromatography silica gel H, HF254, G and GF254. Type G and GF254 contain 2-10% of gypsum contains (CaSO4 · 1 / 2H2O), so they can be made into thin sheets to extend their applications.
