Title:
A data processing device for chromatograph mass spectroscopes, and a program
Document Type and Number:
Japanese Patent JP6132067
Kind Code:
B2
Abstract:
In a chromatogram mass spectrometer's data processing system, if the intensity of a target peak originating from a target component at a target mass-to-charge ratio is equal to or higher than a threshold, the mass-to-charge ratio of a peak having a signal intensity lower than the threshold on the mass spectrum corresponding to the point in time where the target peak appears is designated as a correction mass-to-charge ratio. A mass spectrum at a point in time in the target peak where the signal intensity does not exceed the threshold is acquired. A sensitivity factor is calculated by dividing the strength at the target mass to-charge ratio on this mass spectrum by the strength at the correction mass to-charge ratio on the same spectrum. A mass chromatogram at the correction mass-to-charge ratio is created. This mass chromatogram is multiplied by the sensitivity factor to create a corrected mass chromatogram.
