Abstract:
An example system includes an electron ionization ion source and a mass analyzer. The electron ion source is configured, during operation of the system, to create from sample molecules a beam of ions extending along an ion beam axis. The system also includes a collision cooling chamber comprising a gas manifold and an electric field generator. The cooling chamber defines an entrance aperture and an exit aperture on respective opposing ends of the cooling chamber, the entrance aperture of the cooling chamber being in axial alignment with the ion beam axis. The cooling chamber is configured, during operation of the system, to generate a radio frequency (RF) field within the cooling chamber using the electric field generator, and receive collision gas through the gas manifold to pressurize the cooling chamber.

Claim (Index 1):
A system comprising:\n an ion source including:\n an electron source configured, during operation of the system, to generate a flow of electrons; \n a sample introduction assembly configured, during operation of the system, to transport at least one analyte; \n an ionization chamber having a first input port, a second input port, and an outlet port, \n wherein the first input port is configured, during operation of the system, to receive the flow of electrons from the electron source; \n wherein the second input port is configured, during operation of the system, to receive the at least one analyte from the sample introduction assembly, whereby analyte ions are created by interaction between the at least one analyte and the electrons within an ionization region of the ionization chamber, and whereby the analyte ions exit the ionization chamber through the outlet ports along an ion beam axis; \n wherein the ionization chamber comprises at least two chamber electrodes configured, during operation of the system, to have respective independently controlled voltages applied thereto, \n wherein the at least two chamber electrodes comprise an exit electrode defining the outlet port, \n wherein the exit electrode is configured, during operation of the system, to have an exit electrode voltage applied thereto, \n wherein the exit electrode comprises an upstream surface facing the ionization region, the upstream surface defining a substantially frusto-conical shape having a smaller base and a larger base, the smaller base being proximal to or coincident with the outlet port, \n wherein, during operation of the system, electric fields within the ionization chamber resulting from the voltages applied to the exit electrode and at least one other of electrode act to focus and accelerate analyte ions from the ionization region through the outlet port; and \n a mass analyzer.
