To probe separation mechanism and determination with capillary zone electrophoresis (CZE) and liquid chromatography (LC), nine compounds with identical flavanone skeleton were studied. Optimum separation of LC was attained with gradient of acetonitrile and 5mM phosphate buffer (pH 6.9). For CE, electrolyte buffer was 4.5mM SDS in 32mM sodium tetraborate(More)
The method of liquid-phase microextraction assisted with voltage was developed and applied on determination of quinolones in water sample in this study. Both of the reproducibility and extraction time were improved with the aid of applying voltage. Four analytes in neutral state such as cinoxacin, oxolinic acid, nalidixic acid, and flumequine were extracted(More)
