Abstract: A disruptor apparatus comprises a nozzle comprising: a converging section; a diverging section; and a throat between the converging section and the diverging section. The disruptor apparatus also comprises a holder configured to receive a fluid conduit, which comprises an outlet located in the converging section; and a channel disposed about the holder and configured to guide a gas past the outlet of the fluid conduit, through the converging section, through the throat and into the diverging section where the gas travels at supersonic speed and establishes a standing shock wave in the diverging section. A mass spectrometer and a method are also described.

Abstract: A mass spectrometer system includes a first ion source that produces ions in a first ion stream. The mass spectrometer system includes a second ion source that produces ions in a second ion stream. A capillary receives the first and second ion streams and separately introduces ions in the first and second ion streams into a mass spectrometer channel. A mass analyzer is configured to receive and analyze ions from the channel. In one aspect, the capillary introduces ions in the first and second ion streams into the mass spectrometer channel in alternating sequence.

Abstract: An apparatus for analyzing ions by determining times of flight of the ions includes a flight tube. The apparatus includes a pulser for redirecting ions into the flight tube. The apparatus includes a first detector located at a first position within the flight tube. The apparatus includes a second detector located at a second position within the flight tube, wherein the pulser redirects ions in a first ion stream incident on a first flight path into a first trajectory so that ions in the first ion stream interact with the first detector, and the pulser redirects ions in a second ion stream incident on a second flight path into a second trajectory so that ions in the second ion stream interact with the second detector, and the detectors are configured to detect times of arrival of the ions.

Abstract: A mass spectrometer system includes a first mass spectrometer channel. The mass spectrometer system includes a second mass spectrometer channel. A housing is configured to enclose the first and second mass spectrometer channels within the same chamber. A mass analyzer is coupled with the first and second channels and configured to analyze ion streams received from the first and second channels.
