WebThe fragmentation was observed to occur at lower energies in nanoelectrospray than electrospray. The major product ions are proposed to be formed via an initial neutral elimination of methanol followed be subsequent fragmentation. The low-mass product ions were observed at the same m/z for both monensin A and B. WebThe Origin of Fragmentation Patterns. When the vaporized organic sample passes into the ionization chamber of a mass spectrometer, it is bombarded by a stream of electrons. These electrons have a high enough energy to knock an electron off an organic molecule to form a positive ion. This ion is called the molecular ion - or sometimes the parent ...
