MASS SPECTROSCOPE AND MEASUREMENT SYSTEM PROVIDED WITH THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a practical mass spectroscope for proteome analysis. SOLUTION: In a quadrature acceleration type ion trap-coupling time-of-flight mass spectrometer, a range of a mass-load ratio which can be analyzed at one time is enlarged by providing a means to decrease a speed distribution of ion emitted from an ion trap. An efficiency of a protein identification in a proteome analysis is improved. COPYRIGHT: (C)2008,JPO&INPIT
