WIDE RANGE ELECTRON IMPACT ION SOURCE FOR A MASS SPECTROMETER - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240038522 titled 'WIDE RANGE ELECTRON IMPACT ION SOURCE FOR A MASS SPECTROMETER

Simplified Explanation

The abstract describes a wide-range ion source for a mass spectrometer. It consists of two portions, with the second portion positioned downstream of the first portion. The first portion includes an anode and a first filament that is exposed to the pressure of a process chamber. The second portion includes a tubular anode, a second filament surrounding the tubular anode, an extraction lens, and a focus lens.

  • The first portion of the ion source includes an anode and a first filament that is exposed to the pressure of a process chamber.
  • The second portion of the ion source includes a tubular anode, a second filament surrounding the tubular anode, an extraction lens, and a focus lens.
  • The first filament is positioned proximate to the anode and secured in place relative to the anode.
  • A first electron repeller with a partially circular shape is present.
  • The extraction lens defines an opening and the focus lens conducts ions into a volume.

Potential Applications:

  • Mass spectrometry: The wide-range ion source can be used in mass spectrometers for various applications such as chemical analysis, environmental monitoring, and pharmaceutical research.
  • Elemental analysis: The ion source can be utilized for elemental analysis of samples, providing valuable information about the composition and structure of materials.
  • Forensic analysis: This technology can be applied in forensic laboratories for analyzing trace evidence and identifying unknown substances.

Problems Solved:

  • Improved ionization efficiency: The wide-range ion source enhances the ionization efficiency, allowing for better detection and analysis of ions.
  • Increased sensitivity: The design of the ion source improves the sensitivity of the mass spectrometer, enabling the detection of low abundance ions.
  • Wide range of ionization: The ion source can ionize a wide range of compounds, including both volatile and non-volatile substances.

Benefits:

  • Enhanced analytical capabilities: The wide-range ion source improves the performance of mass spectrometers, enabling more accurate and comprehensive analysis of samples.
  • Increased sensitivity: The higher sensitivity of the ion source allows for the detection of trace amounts of substances, even in complex matrices.
  • Versatility: The ion source can be used for a wide range of applications, making it a valuable tool in various scientific fields.


Original Abstract Submitted

a wide-range ion source for a mass spectrometer comprises a first portion and a second portion that is positioned downstream of the first portion. the first portion includes an anode and a first filament that is positioned proximate the anode and secured in place relative to the anode. the first filament is exposed to a pressure of a process chamber. a first electron repeller has at least a partially circular shape. the second portion includes a tubular anode, a second filament surrounding the tubular anode, an extraction lens defining an opening and a focus lens to conduct ions into a volume.
