Mass spectrometry for fundamental studies in metrology and atomic, nuclear and particle physics requires extreme sensitivity and efficiency as well as ultimate resolving power and accuracy. An overview will be given on the global status of high-accuracy mass spectrometry for fundamental physics and metrology. Three quite different examples of modern mass spectrometric experiments in physics are...

Electrospray ionization (ESI) has become a powerful tool for the analysis of biomolecules by mass spectrometry (MS). The process ESI is difficult to control, and side reactions such as electrochemical can occur during because high voltages applied. Herein, novel on-demand MS method was developed based on discontinuous ion injection-induced miniature system. Highly efficient enabled under low (<...
