Title:
MASS SPECTROMETRY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/109895
Kind Code:
A1
Abstract:
A measurement unit (1) executes product ion scanning measurement for a sample containing a target compound by using, as a precursor ion, a known m/z value of an ion derived from the compound, thereby obtaining profile spectrum data. In a data processing unit (2A), a peak detecting unit (22) detects peaks in the profile spectrum, and for each of the peaks detected, a product-ion m/z-value obtaining unit (23) obtains an m/z value corresponding to the maximum intensity as an m/z value of the product ion. A pseudo-MRM measurement-data extracting unit (24) sets the m/z value of the precursor ion and the m/z value of the product ion as an MRM transition, extracts the maximum intensity at the peak attributable to the product ion as a signal intensity value in the MRM transition, and saves the signal intensity value in a storage unit (25) as pseudo-MRM measurement data. This makes it possible to obtain quantitative information reflecting the concentration of the target compound just by product ion scanning measurement without having to execute MRM measurement.
