英文摘要: A novel click oligo(ethylene glycol) (Click OEG) stationary phase was proposed for constructing two-dimensional reversed-phase/reversed-phase liquid chromatography system (2D-RP/RPLC) combined with C18. The new stationary phase was prepared by immobilization of oligo(ethylene glycol) on silica support via click chemistry. And the resulting material was characterized by FT-IR, solid state CP/MAS C-13 NMR and elemental analysis. The investigation on orthogonality between Click OEG and C18 was performed by geometric approach with a set of testsolutes. The orthogonality reached 68.94%, which is much higher than other combinations. An offline 2DLC system consisted of Click OEG and C18 was constructed and applied to the analysis of a kind of traditional Chinese medicine Lignum Dalbergiae Odoriferae. Excellent separation results validated the high orthogonality between the Click OEG and C18 in the practical separation of complex samples. (C) 2008 Elsevier B.V. All rights reserved.
