The mass spectrum creation means which

摘要

PROBLEM TO BE SOLVED: To provide a liquid chromatograph mass analyzer capable of comparing mass spectra between different conditions even analysis condition is altered during the measurement.;SOLUTION: The liquid chromatograph mass analyzer comprises; a mass spectrum creation part 12 creating a mass spectrum based on a detection signal acquired from an LC/MS analysis part 10; a TIC creation part 13 creating a total ion chromatogram by calculating the total ionic strength of the created mass spectrum at each time; a peak detection part 14 detecting a peak from the TIC created by the TIC creation part 13; and a mass spectrum normalization part 15 normalizing mass spectra from a plurality of time included in each peak, based on the total ionic strength.;COPYRIGHT: (C)2012,JPO&INPIT
