Waters公司产品说明：高效液相色谱(HPLC)及其相关技术的简要介绍说明书 Introduction to GPC Columns, Distributions,Sample Prep., Calibration,What’s New COMPANY CONFIDENTIAL ©2018 Waters Corporation1
22、。Prep-HPLC purification of natural products typically requires one of the following four chromatographic modes: normal phase, reversed-phase, gel permeation chromatography (GPC), and ion exchange chromatography The modes are determined by the stationary phase and of the preparative column being use...
It can be concluded that the developed HPLC method is capable of distinguishing the stability difference between the two phosphate ester bonds characterized on the L-α-GPC chemical structure.doi:10.1016/j.jpba.2020.113468Hongwei ZhaoLing Sun
Gel permeation chromatography Also known as size-exclusion chromatography, gel perme- ation chromatography (GPC) has become a standard tech- nique for isolating compounds of low molecular weight from samples that contain compounds of high molecular weight, such as oil or fats. The separation is ...
