METHOD FOR INTRODUCING IONS BEING ANALYZED INTO ANALYZER WORKING SPACE OF THREE-DIMENSIONAL TRAP-TYPE HYPERBOLOID MASS SPECTROMETER Russian patent published in 1999 - IPC

Abstract RU 2133519 C1

FIELD: hyperboloid mass spectrometry. SUBSTANCE: ions produced beyond analyzer working space are introduced in the latter through one or more narrow channels provided in annular electrode at certain angle to straight line between their introduction point and point of intersection of plain perpendicular to center line of electrode system with this axis that crosses ion introduction point. EFFECT: improved maximum sensitivity and resolving power of device. 4 dwg
