Description

Preparative HPLC is a method that uses high pressure and large flow conveying system to separate sample in high resolution, large inner diameter and high load. It also has been the most popular, most effective and fastest-developing method in relevant technology in the chemical research of natural products for more than ten years. The products obtained by this method are far superior to those obtained by other traditional separation methods in terms of purity, recovery rate and separation efficiency. According to the preparation scale, there are 3 types, namely, semi-preparative HPLC, Gram-grade preparative UPLC and industrial preparative HPLC.
