Abstract
An apparatus for mass analyzing molecules includes a mass spectrometer configured to select precursor ions having a mass to charge ratio range, a metastable species generator configured to generate a metastable species for introduction into the mass spectrometer, and a mass detector configured to detect a mass of the product ions. The apparatus also includes interaction region in the mass spectrometer where the precursor ions fragment into product ions via interaction of the precursor ions with the metastable species.
