STUDY FOR MASS RESOLUTION OF QUADRUPOLE MASS SPECTROMETERS ACCORDING TO THE ROD ELECTRODE ALIGNMENT

摘要

Radio frequency (RF) quadrupole mass spectrometers (QMS) have come to be used in various fields because of their compactness. Ionized specimens are separated while passing through a QMS in accordance with their m/z values. The mass resolution of QMSs must be raised to identify species with high accuracy. The mass resolution is related to the alignment of a QMS's four rod electrodes [1].
