MASS SPECTROMETER AND MEASURING SYSTEM USING SAME

摘要

PROBLEM TO BE SOLVED: To provide a practical mass spectrometer for proteome analysis. SOLUTION: An orthogonal acceleration ion trap-coupled time-of-flight mass spectrometer comprises a means for reducing the velocity distribution of ions injected by an ion trap to increase a mass/charge ratio range allowable for once analysis. Thus, the efficiency of identifying protein in proteome analysis is improved. COPYRIGHT: (C)2006,JPO&NCIPI
