Abstract
In a mass spectrometry method for generating product ions from a precursor ion derived from a sample component having a hydrocarbon chain and mass-analyzing the product ion, the precursor ion is irradiated with an oxygen radical or a hydroxy radical and a nitrogen oxide radical to generate product ions, the product ions are separated according to mass-to-charge ratio and the product ions are detected, and a structure of the hydrocarbon chain is inferred based on mass-to-charge ratio of the detected product ions.
