ION TRAP TIME-OF-FLIGHT MASS SPECTROSCOPE

摘要

PROBLEM TO BE SOLVED: To provide an ion trap time-of-flight mass spectroscope of high sensitivity. SOLUTION: Ions fly in a time-of-flight mass spectrometry section 9 (time-of-flight mass spectrometry means) and are transported to an MCP (detector) 8 efficiently by varying the period of high-voltage pulses applied to a PUSH electrode 6 according to the distribution of the number of ions at a multi-pole section 5. Ions are transported to the MCP (detector) 8 efficiently, thus achieving the ion trap time-of-flight mass spectroscope for obtaining high-sensitivity mass spectra. COPYRIGHT: (C)2008,JPO&INPIT
