Different ion mobility technologies with representative illustrations of separation mechanisms, applied field, and gas dynamics. CCS, collision cross section; DMA, differential mobility analyzer; ...

The Nature Index 2024 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Although ion mobility can separate ions very well, it still has some limitations. Since accurate experimental CCS determination in untargeted analysis usually requires reference CCS from standards.

When ion mobility spectrometry (IMS) and mass spectrometry (MS) were first combined in a commercial instrument more than a decade ago, users had limited options. If they wanted the analytical power ...

Wave of the future: Unlike today’s reactors, a traveling-wave reactor requires very little enriched uranium, reducing the risk of weapons proliferation. (Click here for a larger diagram, also on page ...
