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.

Mass spectrometry by detecting positively and negatively charged 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.

Integrated mass spectrometry systems

Mass spectrometers and methods for measuring information about samples using mass spectrometry are disclosed.

High pressure mass spectrometry systems and methods

Mass spectrometry systems include a core featuring an ion source, an ion trap, and an ion detector connected along a gas path, a pressure regulation subsystem connected to the gas path and configured to regulate a gas pressure in the gas path, a sample pre-concentrator connected to the gas path, where the sample pre-concentrator includes an adsorbent material, and a controller connected to the sample pre-concentrator, where during operation of the system, the controller is configured to heat sample particles adsorbed on the adsorbent material to desorb the particles from the adsorbent material and introduce the desorbed particles into the gas path, and a pressure difference between a gas pressure in the sample pre-concentrator and a gas pressure in at least one of the ion source, the ion trap, and the ion detector when the desorbed particles are introduced into the gas path is 50 mTorr or less.

Sample collection in compact mass spectrometry systems

Compact mass spectrometer

An apparatus and method for obtaining a physiological measurement associated with a user using a portable device is disclosed herein. Information displayed on a touch-sensitive display of the portable device specifies the contact area(s) on the portable device for a user to touch. One or more areas on the portable device and/or a detachable device connected to the portable device comprise conductive areas for measuring the resistance or impedance of the user's body between those conductive areas.
