Reversed-phase high performance liquid chromatography (HPLC), conventional gel permeation chromatography (GPC), and gel permeation chromatography coupled with a multiangle laser light scattering photometer (GPC–MALLS) were used for the analysis of epoxy resins based on bisphenol A. Compounds co...
HPLC–ELSD/PDA combined with HPSEC–MALLS–RIDmolecular weightquality markers (Q-marker)red ginseng polysaccharidesRed ginseng (RG) has been extensively utilized in Asian countries due to its pharmacological effects. For the quality evaluation of RG, small molecules, such as ginsenosides, have been ...
radius plot or molar mass versus elution volume plot.The molar mass distribution determined by HPLC was compared with that obtained by GPC-MALLS.Molar mass averages measured by means of GPC,GPC-MALLS,vapor pressure osmometry (VPO),and end group analysis (EG) were compared and the differences ...
HPLC–ELSD/PDA combined with HPSEC–MALLS–RID could be used to determine the contents of disaccharides, molecular weights, and compositional monosaccharides of RG polysaccharides, which could be used for quality control, and this is a new view on the sugar marker to quality differentiation of ...
