The chromatographic equipment of Jiangyin Chuangtong Chromatography Equipment Co., Ltd. is very difficult to efficiently purify these primary products, and the grade of the product is extremely difficult to improve. However, industrial chromatography technology can easily achieve a high degree of purification. At the same time, many target products have low concentrations in raw materials, high impurity concentrations, and many types. To extract high-purity target products from these raw materials, industrial chromatography techniques can only be used. The technology has achieved good results after being applied in biochemical and fine chemical fields.
