Abstract

We propose the design of a compact Mattauch–Herzog ion-optical system featuring a double-focusing static mass spectrometer with a cylindrical electrostatic deflector. This system offers second-order angle focusing and first-order energy focusing along the focal line. The collimating system ensures the optimal vertical acceptance of the mass analyzer and maximum ion transmission within the working mass range. The described ion-optical system serves as a foundation for small-sized mass spectrometers, weighing up to ~50 kg, including turbo-molecular and foreline pumps, while maintaining high analytical performance.

优化用于医学诊断的便携式静态质谱仪的离子光学设计

摘要

我们提出了一种紧凑型 Mattauch-Herzog 离子光学系统的设计，该系统具有带圆柱形静电偏转器的双聚焦静态质谱仪。该系统提供二阶角度聚焦和沿焦线的一阶能量聚焦。准直系统确保质量分析仪的最佳垂直接受度和工作质量范围内的最大离子传输。所描述的离子光学系统是小型质谱仪的基础，重量可达约 50 kg，包括涡轮分子泵和前级泵，同时保持高分析性能。
