Sensitivity Measurements for Parent and Daughter Ions of Peptides in a Reflecting Time-of-Flight Mass Spectrometer
High sensitivity is important in the mass spectrometry of biomolecules since many of them are available only in very small quantities. A time-of-flight mass spectrometer has the advantage that ions of all masses are detected at the same time, without scanning; also the instrument transmission is usually high. The recent introduction of ion mirrors in these instruments has improved their resolution and enabled measurements of daughter ions from metastable decay .
