1.The complexes formed in organic solvent, aqueous and micellar solution are injected into chromatographic system or the metal ions are injected into the eluent containing the chelating agent.
2.In this paper, oligosaccharides in soybean flour were determined by HPLC on an ODS column, using pure water as eluent.
3.Then the eluent which got from above conditions was dehydrogenized by vacuum freezing drying method, the tan powder of BLF was collected.
4.Retention behavior of alkali metals, ammonium ion and alkyl amines on a sulfonic cation-exchange resin column with organic acid and inorganic acid as eluent was studied.
5.The eluent is changed in a regular manner starting with a nonpolar solvent and gradually replacing it by a more polar one.
6.Objective to study the influence of eluent of different polarity on triptolide content.
7.After the methanol phase extracted from pulp is treated by pocket resin, 50% alcohol eluent inhibitory is strongest.
