Mass spectrometry by detecting positively and negatively charged particles
15 Nov 22
The disclosure features mass spectrometry systems and methods that include an ion source, an ion trap, a detector subsystem featuring first and second detector elements, and a controller electrically connected to the ion source, the ion trap, and the detector subsystem and configured so that during operation of the system, the controller: applies an electrical signal to the ion source to generate positively and negatively charged particles from sample particles in the system; applies an electrical signal to the ion trap to eject a plurality of particles from the ion trap through a common aperture of the ion trap, and determines information about the sample particles based on first and second electrical signals generated by the ejected particles.

The disclosure features mass spectrometry systems that include: an ion source; a module featuring an ion trap, an ion detector, and a module housing that at least partially surrounds the ion trap and the ion detector; and a vacuum pump featuring a housing having a recess dimensioned to receive the module, so that when the module is positioned within the recess of the vacuum pump housing, a portion of the module is surrounded by the vacuum pump housing, and during operation of the system, the ion source, ion trap, ion detector, and vacuum pump are connected along a common gas flow path and heat is transferred from the vacuum pump to the module.
