| Abstract: | This paper introduces the usage of HPLC/MS(High Performarce Liquid Chromatography/Mass Spectrometry) with ESI(Electrospray Ionization) and APCI(Atmospheric Pressure Chemical Ionization) as interface. HPLC was applied to separate Marbxacin or alpha_terthienyl from matrixs. Coupled with on_line mass spectrometry, chromatographic peaks were assigned according to their mass spectrometry. Practical problems such as the selection of ESI or APCI,the selection of mobile phase, the flow rate and temperature of drying gas were also discussed. |
