摘要： PROBLEM TO BE SOLVED: To provide a mass spectroscope capable of improving sensitivity at mass spectrometric analysis, attenuating noise and improving sensitivity at MS n analysis. SOLUTION: Direct current voltage is superposed on alternating current voltage to be impressed on a second multipolar ion guide 35 so that ions pass through the second multipolar ion guide 35 during the period when the ions are accumulated at an ion trap part 40. At that time, kinetic energy of the ions is so set that accumulation efficiency of the ion trap part 40 is heightened, which results in improvement of measurement sensitivity. During the period when the ions accumulated in the ion trap part 40 are operated and exhausted, impression of the direct current voltage is stopped so that the ions are held inside and prevented from passing through the second multipolar ion guide 35. The ions measured stay inside the ion guide 35 without passing through it, so that new ions will not enter the ion trap part 40 enabling the noise to be attenuated. COPYRIGHT: (C)2006,JPO&NCIPI
