In the present work, an on-line dual focusing technique based on field-enhance sample injection (FASI) and dynamic pH junction (DypH) was developed for the analysis of two 5-hydroxy-tryptamine type 3 receptor (5-HT 3 ) antagonists ondansetron (Ond) and tropisetron (Tro) by capillary electrophoresis with amperometric detection (CE-AD) system. By preparing the sample in a lower conductivity...
It is difficult to detect biogenic amines (BAs) in biological fluids because of their very low concentrations. In this paper, we reported an on‐line sample preconcentration method in CE‐amperometric detection (CE‐AD) based on a dynamic pH junction, and a concentration enhancement of approximately 100‐fold was achieved compared with the classical CE‐AD methods in the simultaneous analysis of six BAs...
