Title:
複数の飛行経路を有する飛行時間型質量分析器
Document Type and Number:
Japanese Patent JP2006511912
Kind Code:
A
Abstract:
A TOF mass analyzer having multiple flight paths is described. The TOF mass analyzer includes a pulsed ion source that generates a packet of ions and that accelerates the packet of ions. An ion deflector directs a first group of ions from the packet of ions to a first ion path, and a second group of ions to a second ion path for each of a first and second predetermined time interval after the pulsed ion source generates the packet of ions. A first TOF mass separator separates the first group of ions according to their mass to-charge ratio and a first detector is positioned to receive the first group of ions A second TOF mass separator separates a second group of ions according to their mass to-charge ratio and a second detector is positioned to receive the second group of ions. Additional ion paths may be employed, and any type of TOF mass separator may be used in each ion path.
