This review is devoted to trapping mass spectrometry wherein ions are confined by electromagnetic fields for prolonged periods of time within limited volume, with mass measurement taking place within the same volume. Three major types of trapping mass spectrometers are discussed, specifically radiofrequency ion trap, Fourier transform ion cyclotron resonance and Orbitrap. While these three branches are intricately interwoven with each other over their recent history, they also differ greatly in their fundamentals, roots and historical origin. This diversity is reflected also in the difference of viewpoints from which each of these directions is addressed in this review. Following the theme of the issue, we focus on developments mainly associated with the country of Germany but, at the same time, we use this review as an illustration of the rapidly increasing globalization of science and expanding multi‐national collaborations.

现代质谱中的离子阱

这篇综述致力于捕获质谱法，其中离子在有限的体积内被电磁场限制了很长的一段时间，而质量测量则在相同的体积内进行。讨论了三种主要的捕集质谱仪，分别是射频离子阱，傅立叶变换离子回旋共振和Orbitrap。尽管这三个分支在其最近的历史中错综复杂地交织在一起，但它们的基本原理，根源和历史渊源也大不相同。这种差异还反映在本综述中针对这些方向所针对的不同观点上。按照问题的主题，我们将重点放在主要与德国国家有关的事态发展上，但与此同时，
