| Abstract: | Field-amplified sample injection and sweeping-micellar electrokinetic chromatography(FASI-sweeping-MEKC) was used in the simultaneous separation and determination of caffeic acid and chlorogenic acid in honeysuckle.Effects of experimental conditions,such as concentration of SDS,injection voltage,injection time ratio of water to sample,injection time,composition and concentration of background electrolyte on separation efficiency were optimized.The optimal conditions were as follows:separation column:an unco... |
