Abstract
In a method for mass spectrometry, a plurality of juxtaposed chromatography apparatus connected to a mass spectrometer start eluting at a predetermined time difference and the following mass spectrometer conducts mass spectrometry. A chromatogram in a preceding chromatography apparatus is analyzed on real time base and results of the analysis are used on real time base to change an elusion condition of a succeeding chromatography apparatus. A mass spectrometric system suitable for carrying out the method is also provided.
