Abstract english

A technique which uses polymer nanoparticles as interaction phase in capillary electrochromatography (CEC)-ESI-MS was described. A continuous full filling technique in which nanoparticles were suspended in the entire electrolyte volume as well as conventional partial filling technique were presented. The results verified that polymer nanoparticles suspended in electrolyte can be used as pseudo stationary phase in CEC with ESI-MS detection using continuous full filling and partial filling techniques. The sample molecules were separated from the nanoparticles in the orthogonal ESI-interface and MS-detection was performed despite the continuous flow of nanoparticles into the interface.
