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 ...

LCGC International provides separation science insights, including liquid chromatography (HPLC), gas chromatography (GC), and ...

This channel electron multiplier amplifies the faint signals generated in some types of mass spectrometry and other precision analytical techniques. Electrons are focused into the curved device, where ...

We demonstrate the coupling of desorption electro-flow focusing ionization (DEFFI) with in-source collision induced dissociation (CID) for the mass spectrometric (MS) detection and imaging of ...
