Summary: | The invention discloses a method for continuously separating synthetic pigments in multiple modes with pCEC (pressurized capillary electrochromatography). According to the method, a multi-mode capillary separating column is adopted, and a high-voltage electric field and liquid-phase high voltage are applied to the separating column simultaneously, so that the synthetic pigments are firstly subjected to first-dimension pressurized capillary electrophoresis separation in a hollow capillary area with the inner surface exposed and are continuously transferred to a capillary chromatographic column area filled with chromatography filler for second-dimension pCEC separation, and electrophoresis-electrochromatography multimode continuous separation of multiple components on the same separation column is realized; the multimode capillary separation column is seamlessly and continuously constituted by a section of quartz capillary with the inner wall exposed and a section of capillary chromatographic column.
