“…This setup is of continued popularity and relevance in physics, whenever it is important to have a near‐ideal relationship between mass and frequency. Gerz et al discuss the details of such a trap and the influence of various perturbations on the frequencies of ions for a case without image charge detection.…”

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.

“…The slopes are 0.0460(33) and 0.0429 (31) Hz/h for He ÷ and D r , respectively. The presence of several ions in the trap would shift the resonance frequency by space charge [5]. We have measured the shift in v; to 0.023(18)Hz if a second ion of the same mass is simultaneously confined.…”

“…amplitude which reduces the time-of-flight by 10-15%. The theoretical lineshape, which accounts for residual trap imperfections, is rather complicated [5]. For simplicity we choose to fit our data by a Gaussian which does not change the difference of center frequencies for both ions within the given limits of error.…”
