Title: Plasma ion source three-dimensional quadrupole mass spectrometer
Inventor: TERUI YASUSHI
IPC: G01N27/62
Filed: 2001-10-31
Abstract: PROBLEM TO BE SOLVED: To provide a plasma ion source three-dimensional quadrupole mass spectrometer capable of conducting accurate and efficient quantitative analysis without remarkably changing structure. SOLUTION: Measurement starts in step S1 and measurement ions of only one mass number are entrapped in a three-dimensional quadrupole mass spectrograph in step S2. Since there arises a case where ions of precisely one mass number alone cannot be entrapped, only ions of the specified one mass number are discharged in step 3. The number of ions discharged is monitored in step 4, the number of measured ions is compared with and the number of ions that can be entrapped for every mass number stored in a memory means. If the number of ions measured in step S5 is fewer than the number of ions that can be entrapped, actual measurement is conducted in step S7. If the number of ions measured in step S5 is more than the number of ions that can be entrapped, entrapping time is varied in step 6 and measurement is returned to step S2.  In this manner, an accurate and efficient quantitative analysis is made possible.
