摘要： A method of interfacing atmospheric pressure ion sources, including electrospray and desorption electrospray ionization sources, to mass spectrometers, for example miniature mass spectrometers, in which the ionized sample is discontinuously introduced into the mass spectrometer. Discontinuous introduction improves the match between the pumping capacity of the instrument and the volume of atmospheric pressure gas that contains the ionized sample. The reduced duty cycle of sample introduction is offset by operation of the mass spectrometer under higher performance conditions and by ion accumulation at atmospheric pressure.

摘要： An atmospheric pressure ion source, employing the principle of electrospray ionization, chemical ionization, or photo-ionization, comprises a spray probe for spraying a liquid into an ionization chamber and has an exhaust port through which residual spray mist and waste gas, such as evaporated solvent, are extracted. The ion source further comprises an exhaust system comprising a conduit which is connected to the exhaust port. The conduit has a transition from a first cross-section to a second cross section at a point downstream of the exhaust port wherein the second cross section is reduced in relation to the first cross section. Gas is injected via a gas injector into the conduit in a region of the transition to create a low pressure region that removes unwanted material from the chamber.

摘要： A mass spectrometer system is provided that is configurable for operation in both a Kinetic Energy Discrimination (KED) and Dynamic Reaction Cell (DRC). A pressurized or collision cell included in the mass spectrometer encloses a quadrupole and is coupled to a source of both inert and reactive gas. To operate in the KED mode, the collision cell can be filled with a quantity of the inert gas and an energy barrier formed between the collision cell and a downstream mass analyzer. Interferer ions collided with the inert gas can lose on average more energy relative to analyte ions of the same mass to charge ratio and can thus be trapped by the energy barrier in greater proportions. To operate instead in the DRC mode, the collision cell can be filled with a quantity of gas that is reactive with the interferer ions only. Mass filtering of the product ions can then transmit proportionally more of the analyte ions to the downstream mass analyzer. A mode controller coordinates the two modes of operation.
