By a News Reporter-Staff News Editor at Science Letter -- Researchers detail new data in Capillary Electrophoresis. According to news reporting out of Jinan, People's Republic of China, by NewsRx editors, research stated, "In this paper, surfactant-coated multi-walled carbon nanotubes (SC-MWNTs) have been proposed as a novel pseudostationary phase (PSP) to enhance the separation of isoquinoline alkaloids in nonaqueous capillary electrophoresis (NACE). Several parameters affecting NACE separation were studied including the MWNT concentration, the electrolyte concentration, pH* and the separation voltage."
Our news journalists obtained a quote from the research from the School of Chemistry, "In comparison to conventional NACE, the addition of an MWNT dispersion using surfactant solutions in the electrolyte produced an important enhancement in the resolution due to the pi-pi interactions between the analytes and the surface of the carbon nanotubes. Using SC-MWNTs (6 mu g mL(-1)) as a PSP in the background electrolyte (BGE) (i.e., 20mM sodium acetate in methanol-acetonitrile (80:20, v/v)) provided the complete separation of five alkaloids."
According to the news editors, the research concluded: "Finally, the developed method has been successfully applied to the detection and quantification of the tested compounds of Rhizoma Coptidis."
