The Finnigan LTQ FT from Thermo is a hybrid mass spectrometer that combines linear ion trap and FT-ion cyclotron resonance (FT-ICR) technologies in a single instrument.

This paper builds a portable digital ion trap mass spectrometer prototype by designing the vacuum system, control circuit system, and host computer of the ion trap mass spectrometer. Dextromethorphan ...

Abstract: We demonstrate a 2D beam-steering device in SiN based on a large focusing grating, achieving a steering range of 3.2∘ ×46∘ , with discrete steps in azimuth. Despite the curved geometry, it ...

It is believed that ion current rectification (ICR), a property that assures preferential ionic transport in one direction, can only be observed in nanopores when the pore size is comparable to the ...
