英文摘要	In this paper, several factors that could lead to the appearance of false peak were investigated by using on-line sample sweeping technique under different experimental conditions. The tested analytes were buflomedil hydrochloride, ephedrine hydrochloride, benzyl alcohol, vanillin, p-hydroxybenzaldehyde and m-methylphenol. Results showed that among the six compounds, three of diem, i.e., buflomedil hydrochloride, ephedrine hydrochloride and benzyl alcohol Win cause Use peaks to appear when sample injection time is long, sodium dodecyl sulfate (SDS) concentration is high and there is pH gradient between cathode and anode. In order to avoid the appearance of false peak, the pH gradient should be avoided.
