Liquid phase ghost peak trapping column ispacked by high purity activated carbon, with large specific surface area andstrong adsorption capacity, which can effectively remove non-polar and weaklypolar impurities in the mobile phase, especially the mobile phase with addedbuffer salts and acids to reduce the appearance of ghost peaks. It has a longservice life and is suitable for liquid chromatography gradient elution, whichis widely used in the field of drug quality control.
