Title:
飛行時間型質量分析方法及び装置
Document Type and Number:
Japanese Patent JP5226824
Kind Code:
B2
Abstract:
To provide a time-of-flight mass spectrometry apparatus in which convergence of ions in vertical direction is improved, and connection to an orthogonally accelerating ion source is achieved for improving sensitivity.
The time-of-flight mass spectrometry apparatus includes: an ion source 10 to emit a plurality of ions in pulse; an analyzer to achieve the spiral orbit; and a detector 15 to detect the ions. For achieving the spiral orbit, the analyzer is constituted of a plurality of laminated toroidal electric fields.
