Locke Lord LLP
Mass spectrometry analysis method and mass spectrometry system
The invention provides a mass spectrometry analysis method and a mass spectrometry system. During implementation of the mass spectrometry analysis method, intensity data of the daughter ions, a first parameter of the daughter ions associated with the first physicochemical property, and a second parameter of the daughter ions associated with the second physicochemical property are all recorded to form a spectrogram data set. In a deconvolution step, the spectrogram data set is deconvoluted to categorize the daughter ions from the same parent ion according to two-dimensional features including the first parameter and the second parameter. In the above manner, the mass spectrometry analysis method and the mass spectrometry system provided by the invention can detect ions that partially overlap spectral peaks of other ions significantly, thereby improving the qualitative and quantitative ability of data analysis for data independent acquisition.
