The effects of molecular weight and Ion lifetimes on the extent of fragmentation observed In mass spectra of compounds In the mass range 500–5800 have been studied. Fragmentation of large Ions over long periods of time can be observed as coherent peaks In time-of-flight spectra when delayed Ion extraction techniques are employed. The Implications for the design of future high-mass Instruments are discussed.
