Abstract
A practical mass spectrometer for proteome analysis is provided. In an ion trap-connected, orthogonal acceleration type time-of-flight mass spectrometer, the mass-to-charge ratio range that may be analyzed by one procedure is increased by providing means for reducing the velocity of ions ejected from an ion trap. The efficiency in protein identification in proteome analysis is thereby improved.
