Abstract

The purpose of the presentation is to develop a new and universe technology for protein analysis in one minute by HPLC, called as one minute-liquid chromatography (OMLC). OMLC includes: (1) the theoretical basis of two variables of substance retention under gradient elution in liquid chromatography; (2) methodology of integrating all assisted operations for substance separation together by online manner in liquid chromatography (LC); (3) a kind of special column whose length is smaller than its inner diameter, called as  chromatographic cake (CCK), to be employed for separation unit; (4) several examples for ultra-separation of proteins, peptides , and common small solutes to be tested by reversed phase liquid chromatography, hydrophobic interaction chromatography, ion-exchange chromatography, resulting in successfully complete five separation less in 10 min.
