Title: MASS SPECTROMETER
Abstract:
This mass spectrometer is provided with: a precursor ion candidate selection unit 42 which selects precursor ion candidates from mass spectral data; a product ion scan measurement condition determination unit 43 which configures product ion scan measurement conditions by combining precursor ion candidates and multiple cleavage energy candidate values; a product ion spectral data acquisition unit 44 which implements MS/MS measurement to acquire product ion spectral data; a compound database file creation unit 45 which creates a compound database file which associates product ion scan measurement conditions and product ion spectral data; and an MRM measurement condition candidate creation unit 46 which extracts product ions from all product ion spectral data in descending order of mass peak intensity and creates MRM measurement condition candidates which include a product ion mass-to-charge ratio, a precursor ion mass-to-charge ratio, and a cleavage energy candidate value.
